string
Additional attributes associated with the connection. Each attribute is specified as a name-value pair associated by an equal sign (=). Multiple attributes are separated by a semicolon (;) with no additional white space. For information on the attributes available for connecting your source or target endpoint, see Working with AWS DMS Endpoints in the AWS Database Migration Service User Guide.
string
An AWS KMS key identifier that is used to encrypt the connection parameters for the endpoint.
If you don't specify a value for the KmsKeyId parameter, then AWS DMS uses your default encryption key.
AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS Region.
list
One or more tags to be assigned to the endpoint.
(dict) --
A user-defined key-value pair that describes metadata added to an AWS DMS resource and that is used by operations such as the following:
AddTagsToResource
ListTagsForResource
RemoveTagsFromResource
Key (string) --
A key is the required name of the tag. The string value can be 1-128 Unicode characters in length and can't be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regular expressions: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
Value (string) --
A value is the optional value of the tag. The string value can be 1-256 Unicode characters in length and can't be prefixed with "aws:" or "dms:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regular expressions: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
string
The Amazon Resource Name (ARN) for the certificate.
string
The Secure Sockets Layer (SSL) mode to use for the SSL connection. The default is none
string
The Amazon Resource Name (ARN) for the service access role that you want to use to create the endpoint.
string
The external table definition.
dict
Settings in JSON format for the target Amazon DynamoDB endpoint. For information about other available settings, see Using Object Mapping to Migrate Data to DynamoDB in the AWS Database Migration Service User Guide.
ServiceAccessRoleArn (string) -- [REQUIRED]
The Amazon Resource Name (ARN) used by the service access IAM role.
dict
Settings in JSON format for the target Amazon S3 endpoint. For more information about the available settings, see Extra Connection Attributes When Using Amazon S3 as a Target for AWS DMS in the AWS Database Migration Service User Guide.
ServiceAccessRoleArn (string) --
The Amazon Resource Name (ARN) used by the service access IAM role. It is a required parameter that enables DMS to write and read objects from an 3S bucket.
ExternalTableDefinition (string) --
Specifies how tables are defined in the S3 source files only.
CsvRowDelimiter (string) --
The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n ).
CsvDelimiter (string) --
The delimiter used to separate columns in the .csv file for both source and target. The default is a comma.
BucketFolder (string) --
An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .
BucketName (string) --
The name of the S3 bucket.
CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .
Note
For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .
To use SSE_S3 , you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode , provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
Note
AWS DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
Note
This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
Note
AWS DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
Note
AWS DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.
When ParquetTimestampInMillisecond is set to true or y , AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
Note
AWS DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.
Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.
CdcInsertsAndUpdates (boolean) --
A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.
For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
DatePartitionEnabled (boolean) --
When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitoning, see Using date-based folder partitioning
DatePartitionSequence (string) --
Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .
DatePartitionDelimiter (string) --
Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .
dict
The settings in JSON format for the DMS transfer type of source endpoint.
Possible settings include the following:
ServiceAccessRoleArn - The IAM role that has permission to access the Amazon S3 bucket.
BucketName - The name of the S3 bucket to use.
CompressionType - An optional parameter to use GZIP to compress the target files. To use GZIP, set this value to NONE (the default). To keep the files uncompressed, don't use this value.
Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string,CompressionType=string
JSON syntax for these settings is as follows: { "ServiceAccessRoleArn": "string", "BucketName": "string", "CompressionType": "none"|"gzip" }

Specifies the destination of the archived redo logs. The value should be the same as the DEST_ID number in the v$archived_log table. When working with multiple log destinations (DEST_ID), we recommend that you to specify an archived redo logs location identifier. Doing this improves performance by ensuring that the correct logs are accessed from the outset.
AdditionalArchivedLogDestId (integer) --
Set this attribute with archivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, AWS DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.
AllowSelectNestedTables (boolean) --

Password (string) --
Endpoint connection password.
ReadBackupOnly (boolean) --
When this attribute is set to Y , AWS DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.
SafeguardPolicy (string) --
Use this attribute to minimize the need to access the backup log and enable AWS DMS to prevent truncation using one of the following two methods.
Start transactions in the database: This is the default method. When this method is used, AWS DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.
Exclusively use sp_repldone within a single task : When this method is used, AWS DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one AWS DMS task can access the database at any given time. Therefore, if you need to run parallel AWS DMS tasks against the same database, use the default method.
ServerName (string) --
Fully qualified domain name of the endpoint.
Username (string) --
Endpoint connection user name.
UseBcpFullLoad (boolean) --

CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .
Note
For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .
To use SSE_S3 , you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode , provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
Note
AWS DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
Note
This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
Note
AWS DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
Note
AWS DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.
When ParquetTimestampInMillisecond is set to true or y , AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
Note
AWS DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.
Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.
CdcInsertsAndUpdates (boolean) --
A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.
For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
DatePartitionEnabled (boolean) --
When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitoning, see Using date-based folder partitioning
DatePartitionSequence (string) --
Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .

AddSupplementalLogging (boolean) --
Set this attribute to set up table-level supplemental logging for the Oracle database. This attribute enables PRIMARY KEY supplemental logging on all tables selected for a migration task.
If you use this option, you still need to enable database-level supplemental logging.
ArchivedLogDestId (integer) --
Specifies the destination of the archived redo logs. The value should be the same as the DEST_ID number in the v$archived_log table. When working with multiple log destinations (DEST_ID), we recommend that you to specify an archived redo logs location identifier. Doing this improves performance by ensuring that the correct logs are accessed from the outset.
AdditionalArchivedLogDestId (integer) --
Set this attribute with archivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, AWS DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.
AllowSelectNestedTables (boolean) --
Set this attribute to true to enable replication of Oracle tables containing columns that are nested tables or defined types.
ParallelAsmReadThreads (integer) --
Set this attribute to change the number of threads that DMS configures to perform a Change Data Capture (CDC) load using Oracle Automatic Storage Management (ASM).

ReplacePathPrefix (boolean) --
Set this attribute to true in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This setting tells DMS instance to replace the default Oracle root with the specified usePathPrefix setting to access the redo logs.
EnableHomogenousTablespace (boolean) --
Set this attribute to enable homogenous tablespace replication and create existing tables or indexes under the same tablespace on the target.
DirectPathNoLog (boolean) --
When set to true , this attribute helps to increase the commit rate on the Oracle target database by writing directly to tables and not writing a trail to database logs.
ArchivedLogsOnly (boolean) --
When this field is set to Y , AWS DMS only accesses the archived redo logs. If the archived redo logs are stored on Oracle ASM only, the AWS DMS user account needs to be granted ASM privileges.
AsmPassword (string) --

You set this value as part of the comma-separated value that you set to the Password request parameter when you create the endpoint to access transaction logs using Binary Reader. For more information, see Configuration for change data capture (CDC) on an Oracle source database .
AsmServer (string) --
For an Oracle source endpoint, your ASM server address. You can set this value from the asm_server value. You set asm_server as part of the extra connection attribute string to access an Oracle server with Binary Reader that uses ASM. For more information, see Configuration for change data capture (CDC) on an Oracle source database .
AsmUser (string) --
For an Oracle source endpoint, your ASM user name. You can set this value from the asm_user value. You set asm_user as part of the extra connection attribute string to access an Oracle server with Binary Reader that uses ASM. For more information, see Configuration for change data capture (CDC) on an Oracle source database .
CharLengthSemantics (string) --
Specifies whether the length of a character column is in bytes or in characters. To indicate that the character column length is in characters, set this attribute to CHAR . Otherwise, the character column length is in bytes.
Example: charLengthSemantics=CHAR;
DatabaseName (string) --
Database name for the endpoint.
DirectPathParallelLoad (boolean) --
When set to true , this attribute specifies a parallel load when useDirectPathFullLoad is set to Y . This attribute also only applies when you use the AWS DMS parallel load feature. Note that the target table cannot have any constraints or indexes.
FailTasksOnLobTruncation (boolean) --
When set to true , this attribute causes a task to fail if the actual size of an LOB column is greater than the specified LobMaxSize .
If a task is set to limited LOB mode and this option is set to true , the task fails instead of truncating the LOB data.
NumberDatatypeScale (integer) --
Specifies the number scale. You can select a scale up to 38, or you can select FLOAT. By default, the NUMBER data type is converted to precision 38, scale 10.
Example: numberDataTypeScale=12

Example: retryInterval=6;
SecurityDbEncryption (string) --
For an Oracle source endpoint, the transparent data encryption (TDE) password required by AWM DMS to access Oracle redo logs encrypted by TDE using Binary Reader. It is also the `` TDE_Password `` part of the comma-separated value you set to the Password request parameter when you create the endpoint. The SecurityDbEncryptian setting is related to this SecurityDbEncryptionName setting. For more information, see Supported encryption methods for using Oracle as a source for AWS DMS in the AWS Database Migration Service User Guide .
SecurityDbEncryptionName (string) --
For an Oracle source endpoint, the name of a key used for the transparent data encryption (TDE) of the columns and tablespaces in an Oracle source database that is encrypted using TDE. The key value is the value of the SecurityDbEncryption setting. For more information on setting the key name value of SecurityDbEncryptionName , see the information and example for setting the securityDbEncryptionName extra connection attribute in Supported encryption methods for using Oracle as a source for AWS DMS in the AWS Database Migration Service User Guide .
ServerName (string) --
Fully qualified domain name of the endpoint.

Password (string) --
Endpoint connection password.
ReadBackupOnly (boolean) --
When this attribute is set to Y , AWS DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.
SafeguardPolicy (string) --
Use this attribute to minimize the need to access the backup log and enable AWS DMS to prevent truncation using one of the following two methods.
Start transactions in the database: This is the default method. When this method is used, AWS DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.
Exclusively use sp_repldone within a single task : When this method is used, AWS DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one AWS DMS task can access the database at any given time. Therefore, if you need to run parallel AWS DMS tasks against the same database, use the default method.
ServerName (string) --
Fully qualified domain name of the endpoint.
Username (string) --
Endpoint connection user name.
UseBcpFullLoad (boolean) --
Use this to attribute to transfer data for full-load operations using BCP. When the target table contains an identity column that does not exist in the source table, you must disable the use BCP for loading table option.

DatabaseName (string) --
Database name for the endpoint.
Password (string) --
Endpoint connection password.
Port (integer) --
Endpoint TCP port.
ServerName (string) --
Fully qualified domain name of the endpoint.
SetDataCaptureChanges (boolean) --
Enables ongoing replication (CDC) as a BOOLEAN value. The default is true.
CurrentLsn (string) --
For ongoing replication (CDC), use CurrentLSN to specify a log sequence number (LSN) where you want the replication to start.
MaxKBytesPerRead (integer) --
Maximum number of bytes per read, as a NUMBER value. The default is 64 KB.
Username (string) --
Endpoint connection user name.

An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .
BucketName (string) --
The name of the S3 bucket.
CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .
Note
For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .
To use SSE_S3 , you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode , provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
Note
AWS DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
Note
This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
Note
AWS DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
Note
AWS DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.
When ParquetTimestampInMillisecond is set to true or y , AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
Note
AWS DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.
Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.
CdcInsertsAndUpdates (boolean) --
A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.
For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
DatePartitionEnabled (boolean) --
When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitoning, see Using date-based folder partitioning
DatePartitionSequence (string) --
Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .
DatePartitionDelimiter (string) --
Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .
DmsTransferSettings (dict) --
The settings in JSON format for the DMS transfer type of source endpoint.
Possible settings include the following:
ServiceAccessRoleArn - The IAM role that has permission to access the Amazon S3 bucket.
BucketName - The name of the S3 bucket to use.
CompressionType - An optional parameter to use GZIP to compress the target files. To use GZIP, set this value to NONE (the default). To keep the files uncompressed, don't use this value.
Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string,CompressionType=string
JSON syntax for these settings is as follows: { "ServiceAccessRoleArn": "string", "BucketName": "string", "CompressionType": "none"|"gzip" }

Indicates the number of documents to preview to determine the document organization. Use this setting when NestingLevel is set to "one" .
Must be a positive value greater than 0 . Default value is 1000 .
AuthSource (string) --
The MongoDB database name. This setting isn't used when AuthType is set to "no" .
The default is "admin" .
KmsKeyId (string) --
The AWS KMS key identifier that is used to encrypt the content on the replication instance. If you don't specify a value for the KmsKeyId parameter, then AWS DMS uses your default encryption key.

Shows the partition value within the Kinesis message output, unless the partition type is schema-table-type . The default is false .
PartitionIncludeSchemaTable (boolean) --
Prefixes schema and table names to partition values, when the partition type is primary-key-type . Doing this increases data distribution among Kinesis shards. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same shard, which causes throttling. The default is false .
IncludeTableAlterOperations (boolean) --

Specifies the destination of the archived redo logs. The value should be the same as the DEST_ID number in the v$archived_log table. When working with multiple log destinations (DEST_ID), we recommend that you to specify an archived redo logs location identifier. Doing this improves performance by ensuring that the correct logs are accessed from the outset.
AdditionalArchivedLogDestId (integer) --
Set this attribute with archivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, AWS DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.
AllowSelectNestedTables (boolean) --

Example: charLengthSemantics=CHAR;
DatabaseName (string) --
Database name for the endpoint.
DirectPathParallelLoad (boolean) --
When set to true , this attribute specifies a parallel load when useDirectPathFullLoad is set to Y . This attribute also only applies when you use the AWS DMS parallel load feature. Note that the target table cannot have any constraints or indexes.
FailTasksOnLobTruncation (boolean) --
When set to true , this attribute causes a task to fail if the actual size of an LOB column is greater than the specified LobMaxSize .
If a task is set to limited LOB mode and this option is set to true , the task fails instead of truncating the LOB data.
NumberDatatypeScale (integer) --
Specifies the number scale. You can select a scale up to 38, or you can select FLOAT. By default, the NUMBER data type is converted to precision 38, scale 10.

Password (string) --
Endpoint connection password.
ReadBackupOnly (boolean) --
When this attribute is set to Y , AWS DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.
SafeguardPolicy (string) --
Use this attribute to minimize the need to access the backup log and enable AWS DMS to prevent truncation using one of the following two methods.
Start transactions in the database: This is the default method. When this method is used, AWS DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.
Exclusively use sp_repldone within a single task : When this method is used, AWS DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one AWS DMS task can access the database at any given time. Therefore, if you need to run parallel AWS DMS tasks against the same database, use the default method.

CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .
Note
For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .
To use SSE_S3 , you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode , provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
Note
AWS DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
Note
This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
Note
AWS DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
Note
AWS DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.
When ParquetTimestampInMillisecond is set to true or y , AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
Note
AWS DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.
Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.
CdcInsertsAndUpdates (boolean) --
A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.
For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
DatePartitionEnabled (boolean) --
When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitoning, see Using date-based folder partitioning
DatePartitionSequence (string) --
Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .
DatePartitionDelimiter (string) --
Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .
DmsTransferSettings (dict) --
The settings in JSON format for the DMS transfer type of source endpoint.
Possible settings include the following:
ServiceAccessRoleArn - The IAM role that has permission to access the Amazon S3 bucket.
BucketName - The name of the S3 bucket to use.
CompressionType - An optional parameter to use GZIP to compress the target files. To use GZIP, set this value to NONE (the default). To keep the files uncompressed, don't use this value.
Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string,CompressionType=string

If your date and time values use formats different from each other, set this to auto .
EmptyAsNull (boolean) --
A value that specifies whether AWS DMS should migrate empty CHAR and VARCHAR fields as NULL. A value of true sets empty CHAR and VARCHAR fields to null. The default is false .
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .
Note
For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .
To use SSE_S3 , create an AWS Identity and Access Management (IAM) role with a policy that allows "arn:aws:s3:::*" to use the following actions: "s3:PutObject", "s3:ListBucket"
ExplicitIds (boolean) --
This setting is only valid for a full-load migration task. Set ExplicitIds to true to have tables with IDENTITY columns override their auto-generated values with explicit values loaded from the source data files used to populate the tables. The default is false .

The maximum size (in KB) of any .csv file used to load data on an S3 bucket and transfer data to Amazon Redshift. It defaults to 1048576KB (1 GB).
Password (string) --
The password for the user named in the username property.
Port (integer) --
The port number for Amazon Redshift. The default value is 5439.
RemoveQuotes (boolean) --
A value that specifies to remove surrounding quotation marks from strings in the incoming data. All characters within the quotation marks, including delimiters, are retained. Choose true to remove quotation marks. The default is false .
ReplaceInvalidChars (string) --
A list of characters that you want to replace. Use with ReplaceChars .
ReplaceChars (string) --
A value that specifies to replaces the invalid characters specified in ReplaceInvalidChars , substituting the specified characters instead. The default is "?" .

ServiceAccessRoleArn (string) --
The Amazon Resource Name (ARN) of the IAM role that has access to the Amazon Redshift service.
ServerSideEncryptionKmsKeyId (string) --
The AWS KMS key ID. If you are using SSE_KMS for the EncryptionMode , provide this key ID. The key that you use needs an attached policy that enables IAM user permissions and allows use of the key.
TimeFormat (string) --
The time format that you want to use. Valid values are auto (case-sensitive), 'timeformat_string' , 'epochsecs' , or 'epochmillisecs' . It defaults to 10. Using auto recognizes most strings, even some that aren't supported when you use a time format string.

If you use this option, you still need to enable database-level supplemental logging.
ArchivedLogDestId (integer) --
Specifies the destination of the archived redo logs. The value should be the same as the DEST_ID number in the v$archived_log table. When working with multiple log destinations (DEST_ID), we recommend that you to specify an archived redo logs location identifier. Doing this improves performance by ensuring that the correct logs are accessed from the outset.
AdditionalArchivedLogDestId (integer) --
Set this attribute with archivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, AWS DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.
AllowSelectNestedTables (boolean) --

ReplacePathPrefix (boolean) --
Set this attribute to true in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This setting tells DMS instance to replace the default Oracle root with the specified usePathPrefix setting to access the redo logs.
EnableHomogenousTablespace (boolean) --
Set this attribute to enable homogenous tablespace replication and create existing tables or indexes under the same tablespace on the target.
DirectPathNoLog (boolean) --
When set to true , this attribute helps to increase the commit rate on the Oracle target database by writing directly to tables and not writing a trail to database logs.
ArchivedLogsOnly (boolean) --
When this field is set to Y , AWS DMS only accesses the archived redo logs. If the archived redo logs are stored on Oracle ASM only, the AWS DMS user account needs to be granted ASM privileges.
AsmPassword (string) --

Example: charLengthSemantics=CHAR;
DatabaseName (string) --
Database name for the endpoint.
DirectPathParallelLoad (boolean) --
When set to true , this attribute specifies a parallel load when useDirectPathFullLoad is set to Y . This attribute also only applies when you use the AWS DMS parallel load feature. Note that the target table cannot have any constraints or indexes.
FailTasksOnLobTruncation (boolean) --
When set to true , this attribute causes a task to fail if the actual size of an LOB column is greater than the specified LobMaxSize .
If a task is set to limited LOB mode and this option is set to true , the task fails instead of truncating the LOB data.
NumberDatatypeScale (integer) --
Specifies the number scale. You can select a scale up to 38, or you can select FLOAT. By default, the NUMBER data type is converted to precision 38, scale 10.

For an Oracle source endpoint, the name of a key used for the transparent data encryption (TDE) of the columns and tablespaces in an Oracle source database that is encrypted using TDE. The key value is the value of the SecurityDbEncryption setting. For more information on setting the key name value of SecurityDbEncryptionName , see the information and example for setting the securityDbEncryptionName extra connection attribute in Supported encryption methods for using Oracle as a source for AWS DMS in the AWS Database Migration Service User Guide .
ServerName (string) --
Fully qualified domain name of the endpoint.
Username (string) --
Endpoint connection user name.
SybaseSettings (dict) --
The settings for the SAP ASE source and target endpoint. For more information, see the SybaseSettings structure.
DatabaseName (string) --
Database name for the endpoint.
Password (string) --
Endpoint connection password.
Port (integer) --
Endpoint TCP port.
ServerName (string) --
Fully qualified domain name of the endpoint.
Username (string) --
Endpoint connection user name.

Password (string) --
Endpoint connection password.
ReadBackupOnly (boolean) --
When this attribute is set to Y , AWS DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.
SafeguardPolicy (string) --
Use this attribute to minimize the need to access the backup log and enable AWS DMS to prevent truncation using one of the following two methods.
Start transactions in the database: This is the default method. When this method is used, AWS DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.
Exclusively use sp_repldone within a single task : When this method is used, AWS DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one AWS DMS task can access the database at any given time. Therefore, if you need to run parallel AWS DMS tasks against the same database, use the default method.
ServerName (string) --
Fully qualified domain name of the endpoint.
Username (string) --
Endpoint connection user name.
UseBcpFullLoad (boolean) --

CurrentLsn (string) --
For ongoing replication (CDC), use CurrentLSN to specify a log sequence number (LSN) where you want the replication to start.
MaxKBytesPerRead (integer) --
Maximum number of bytes per read, as a NUMBER value. The default is 64 KB.
Username (string) --
Endpoint connection user name.

ServiceAccessRoleArn (string) -- [REQUIRED]
The Amazon Resource Name (ARN) used by the service access IAM role.
dict
Settings in JSON format for the target Amazon S3 endpoint. For more information about the available settings, see Extra Connection Attributes When Using Amazon S3 as a Target for AWS DMS in the AWS Database Migration Service User Guide.
ServiceAccessRoleArn (string) --
The Amazon Resource Name (ARN) used by the service access IAM role. It is a required parameter that enables DMS to write and read objects from an 3S bucket.
ExternalTableDefinition (string) --
Specifies how tables are defined in the S3 source files only.
CsvRowDelimiter (string) --
The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n ).
CsvDelimiter (string) --
The delimiter used to separate columns in the .csv file for both source and target. The default is a comma.
BucketFolder (string) --
An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .
BucketName (string) --
The name of the S3 bucket.
CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .
Note
For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .
To use SSE_S3 , you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode , provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
Note
AWS DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
Note
This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
Note
AWS DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
Note
AWS DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.
When ParquetTimestampInMillisecond is set to true or y , AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
Note
AWS DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.
Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.
CdcInsertsAndUpdates (boolean) --
A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.
For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

Settings in JSON format for the source and target Microsoft SQL Server endpoint. For information about other available settings, see Extra connection attributes when using SQL Server as a source for AWS DMS and Extra connection attributes when using SQL Server as a target for AWS DMS in the AWS Database Migration Service User Guide.
Port (integer) --
Endpoint TCP port.
BcpPacketSize (integer) --
The maximum size of the packets (in bytes) used to transfer data using BCP.
DatabaseName (string) --
Database name for the endpoint.
ControlTablesFileGroup (string) --
Specify a filegroup for the AWS DMS internal tables. When the replication task starts, all the internal AWS DMS control tables (awsdms_ apply_exception, awsdms_apply, awsdms_changes) are created on the specified filegroup.
Password (string) --
Endpoint connection password.
ReadBackupOnly (boolean) --
When this attribute is set to Y , AWS DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.
SafeguardPolicy (string) --
Use this attribute to minimize the need to access the backup log and enable AWS DMS to prevent truncation using one of the following two methods.
Start transactions in the database: This is the default method. When this method is used, AWS DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.
Exclusively use sp_repldone within a single task : When this method is used, AWS DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one AWS DMS task can access the database at any given time. Therefore, if you need to run parallel AWS DMS tasks against the same database, use the default method.
ServerName (string) --
Fully qualified domain name of the endpoint.
Username (string) --
Endpoint connection user name.
UseBcpFullLoad (boolean) --
Use this to attribute to transfer data for full-load operations using BCP. When the target table contains an identity column that does not exist in the source table, you must disable the use BCP for loading table option.
dict
Settings in JSON format for the source IBM Db2 LUW endpoint. For information about other available settings, see Extra connection attributes when using Db2 LUW as a source for AWS DMS in the AWS Database Migration Service User Guide.
DatabaseName (string) --
Database name for the endpoint.
Password (string) --
Endpoint connection password.
Port (integer) --
Endpoint TCP port.
ServerName (string) --
Fully qualified domain name of the endpoint.
SetDataCaptureChanges (boolean) --
Enables ongoing replication (CDC) as a BOOLEAN value. The default is true.
CurrentLsn (string) --
For ongoing replication (CDC), use CurrentLSN to specify a log sequence number (LSN) where you want the replication to start.
MaxKBytesPerRead (integer) --
Maximum number of bytes per read, as a NUMBER value. The default is 64 KB.
Username (string) --
Endpoint connection user name.

S3Settings (dict) --
The settings for the S3 target endpoint. For more information, see the S3Settings structure.
ServiceAccessRoleArn (string) --
The Amazon Resource Name (ARN) used by the service access IAM role. It is a required parameter that enables DMS to write and read objects from an 3S bucket.
ExternalTableDefinition (string) --
Specifies how tables are defined in the S3 source files only.
CsvRowDelimiter (string) --
The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n ).
CsvDelimiter (string) --
The delimiter used to separate columns in the .csv file for both source and target. The default is a comma.
BucketFolder (string) --
An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn't specified, then the path used is `` schema_name /table_name /`` .
BucketName (string) --
The name of the S3 bucket.
CompressionType (string) --
An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don't use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.
EncryptionMode (string) --
The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .
Note
For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .
To use SSE_S3 , you need an AWS Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:
s3:CreateBucket
s3:ListBucket
s3:DeleteBucket
s3:GetBucketLocation
s3:GetObject
s3:PutObject
s3:DeleteObject
s3:GetObjectVersion
s3:GetBucketPolicy
s3:PutBucketPolicy
s3:DeleteBucketPolicy
ServerSideEncryptionKmsKeyId (string) --
If you are using SSE_KMS for the EncryptionMode , provide the AWS KMS key ID. The key that you use needs an attached policy that enables AWS Identity and Access Management (IAM) user permissions and allows use of the key.
Here is a CLI example: ``aws dms create-endpoint --endpoint-identifier value --endpoint-type target --engine-name s3 --s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``
DataFormat (string) --
The format of the data that you want to use for output. You can choose one of the following:
csv : This is a row-based file format with comma-separated values (.csv).
parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.
EncodingType (string) --
The type of encoding you are using:
RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
PLAIN doesn't use encoding at all. Values are stored as they are.
PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.
DictPageSizeLimit (integer) --
The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.
RowGroupLength (integer) --
The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.
If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).
DataPageSize (integer) --
The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.
ParquetVersion (string) --
The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .
EnableStatistics (boolean) --
A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.
IncludeOpForFullLoad (boolean) --
A value that enables a full load to write INSERT operations to the comma-separated value (.csv) output files only to indicate how the rows were added to the source database.
Note
AWS DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.
For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.
Note
This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
CdcInsertsOnly (boolean) --
A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.
If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
TimestampColumnName (string) --
A value that when nonblank causes AWS DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.
Note
AWS DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.
DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.
For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.
For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.
The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.
When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .
ParquetTimestampInMillisecond (boolean) --
A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.
Note
AWS DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.
When ParquetTimestampInMillisecond is set to true or y , AWS DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.
Currently, Amazon Athena and AWS Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or AWS Glue.
Note
AWS DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.
Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.
CdcInsertsAndUpdates (boolean) --
A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.
For .csv file format only, how these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the AWS Database Migration Service User Guide. .
Note
AWS DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.
CdcInsertsOnly and CdcInsertsAndUpdates can't both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.
DatePartitionEnabled (boolean) --
When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitoning, see Using date-based folder partitioning
DatePartitionSequence (string) --
Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .
DatePartitionDelimiter (string) --
Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .
DmsTransferSettings (dict) --
The settings in JSON format for the DMS transfer type of source endpoint.
Possible settings include the following:
ServiceAccessRoleArn - The IAM role that has permission to access the Amazon S3 bucket.
BucketName - The name of the S3 bucket to use.
CompressionType - An optional parameter to use GZIP to compress the target files. To use GZIP, set this value to NONE (the default). To keep the files uncompressed, don't use this value.
Shorthand syntax for these settings is as follows: ServiceAccessRoleArn=string,BucketName=string,CompressionType=string
JSON syntax for these settings is as follows: { "ServiceAccessRoleArn": "string", "BucketName": "string", "CompressionType": "none"|"gzip" }

Shows the partition value within the Kinesis message output, unless the partition type is schema-table-type . The default is false .
PartitionIncludeSchemaTable (boolean) --
Prefixes schema and table names to partition values, when the partition type is primary-key-type . Doing this increases data distribution among Kinesis shards. For example, suppose that a SysBench schema has thousands of tables and each table has only limited range for a primary key. In this case, the same primary key is sent from thousands of tables to the same shard, which causes throttling. The default is false .

When working with multiple log destinations (DEST_ID), we recommend that you to specify an archived redo logs location identifier. Doing this improves performance by ensuring that the correct logs are accessed from the outset.
AdditionalArchivedLogDestId (integer) --
Set this attribute with archivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, AWS DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.

Password (string) --
Endpoint connection password.
ReadBackupOnly (boolean) --
When this attribute is set to Y , AWS DMS only reads changes from transaction log backups and doesn't read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.
SafeguardPolicy (string) --
Use this attribute to minimize the need to access the backup log and enable AWS DMS to prevent truncation using one of the following two methods.
Start transactions in the database: This is the default method. When this method is used, AWS DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren't truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.
Exclusively use sp_repldone within a single task : When this method is used, AWS DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn't involve any transactional activities, it can only be used when Microsoft Replication isn't running. Also, when using this method, only one AWS DMS task can access the database at any given time. Therefore, if you need to run parallel AWS DMS tasks against the same database, use the default method.
