Information about a query execution.
(dict) --
Information about a single instance of a query execution.
QueryExecutionId (string) --
The unique identifier for each query execution.
Query (string) --
The SQL query statements which the query execution ran.
StatementType (string) --
The type of query statement that was run. DDL indicates DDL query statements. DML indicates DML (Data Manipulation Language) query statements, such as CREATE TABLE AS SELECT . UTILITY indicates query statements other than DDL and DML, such as SHOW CREATE TABLE , or DESCRIBE <table> .
ResultConfiguration (dict) --
The location in Amazon S3 where query results were stored and the encryption option, if any, used for query results. These are known as "client-side settings". If workgroup settings override client-side settings, then the query uses the location for the query results and the encryption configuration that are specified for the workgroup.
OutputLocation (string) --
The location in Amazon S3 where your query results are stored, such as s3://path/to/query/bucket/ . To run the query, you must specify the query results location using one of the ways: either for individual queries using either this setting (client-side), or in the workgroup, using WorkGroupConfiguration . If none of them is set, Athena issues an error that no output location is provided. For more information, see Query Results . If workgroup settings override client-side settings, then the query uses the settings specified for the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
EncryptionConfiguration (dict) --
If query results are encrypted in Amazon S3, indicates the encryption option used (for example, SSE-KMS or CSE-KMS ) and key information. This is a client-side setting. If workgroup settings override client-side settings, then the query uses the encryption configuration that is specified for the workgroup, and also uses the location for storing query results specified in the workgroup. See WorkGroupConfiguration$EnforceWorkGroupConfiguration and Workgroup Settings Override Client-Side Settings .
EncryptionOption (string) --
Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys (SSE-S3 ), server-side encryption with KMS-managed keys (SSE-KMS ), or client-side encryption with KMS-managed keys (CSE-KMS) is used.
If a query runs in a workgroup and the workgroup overrides client-side settings, then the workgroup's setting for encryption is used. It specifies whether query results must be encrypted, for all queries that run in this workgroup.
KmsKey (string) --
For SSE-KMS and CSE-KMS , this is the KMS key ARN or ID.
QueryExecutionContext (dict) --
The database in which the query execution occurred.
Database (string) --
The name of the database used in the query execution.
Catalog (string) --
The name of the data catalog used in the query execution.
Status (dict) --
The completion date, current state, submission time, and state change reason (if applicable) for the query execution.
State (string) --
The state of query execution. QUEUED indicates that the query has been submitted to the service, and Athena will execute the query as soon as resources are available. RUNNING indicates that the query is in execution phase. SUCCEEDED indicates that the query completed without errors. FAILED indicates that the query experienced an error and did not complete processing. CANCELLED indicates that a user input interrupted query execution.
Note
Athena automatically retries your queries in cases of certain transient errors. As a result, you may see the query state transition from RUNNING or FAILED to QUEUED .
StateChangeReason (string) --
Further detail about the status of the query.
SubmissionDateTime (datetime) --
The date and time that the query was submitted.
CompletionDateTime (datetime) --
The date and time that the query completed.

The number of milliseconds that the query took to execute.
DataScannedInBytes (integer) --
The number of bytes in the data that was queried.
DataManifestLocation (string) --
The location and file name of a data manifest file. The manifest file is saved to the Athena query results location in Amazon S3. The manifest file tracks files that the query wrote to Amazon S3. If the query fails, the manifest file also tracks files that the query intended to write. The manifest is useful for identifying orphaned files resulting from a failed query. For more information, see Working with Query Results, Output Files, and Query History in the Amazon Athena User Guide .
TotalExecutionTimeInMillis (integer) --
The number of milliseconds that Athena took to run the query.
QueryQueueTimeInMillis (integer) --
The number of milliseconds that the query was in your query queue waiting for resources. Note that if transient errors occur, Athena might automatically add the query back to the queue.
QueryPlanningTimeInMillis (integer) --
The number of milliseconds that Athena took to plan the query processing flow. This includes the time spent retrieving table partitions from the data source. Note that because the query engine performs the query planning, query planning time is a subset of engine processing time.

The number of milliseconds that Athena took to finalize and publish the query results after the query engine finished running the query.
WorkGroup (string) --
The name of the workgroup in which the query ran.
EngineVersion (dict) --
The engine version that executed the query.
SelectedEngineVersion (string) --
The engine version requested by the user. Possible values are determined by the output of ListEngineVersions , including Auto. The default is Auto.
EffectiveEngineVersion (string) --
Read only. The engine version on which the query runs. If the user requests a valid engine version other than Auto, the effective engine version is the same as the engine version that the user requested. If the user requests Auto, the effective engine version is chosen by Athena. When a request to update the engine version is made by a CreateWorkGroup or UpdateWorkGroup operation, the EffectiveEngineVersion field is ignored.

The engine version setting for all queries on the workgroup. Queries on the AmazonAthenaPreviewFunctionality workgroup run on the preview engine regardless of this setting.
SelectedEngineVersion (string) --
The engine version requested by the user. Possible values are determined by the output of ListEngineVersions , including Auto. The default is Auto.
EffectiveEngineVersion (string) --
Read only. The engine version on which the query runs. If the user requests a valid engine version other than Auto, the effective engine version is the same as the engine version that the user requested. If the user requests Auto, the effective engine version is chosen by Athena. When a request to update the engine version is made by a CreateWorkGroup or UpdateWorkGroup operation, the EffectiveEngineVersion field is ignored.
NextToken (string) --
A token generated by the Athena service that specifies where to continue pagination if a previous request was truncated. To obtain the next set of pages, pass in the NextToken from the response object of the previous page call.

string
[REQUIRED]
The specified workgroup that will be updated.
string
The workgroup description.
dict
The workgroup configuration that will be updated for the given workgroup.
EnforceWorkGroupConfiguration (boolean) --
If set to "true", the settings for the workgroup override client-side settings. If set to "false" client-side settings are used. For more information, see Workgroup Settings Override Client-Side Settings .
ResultConfigurationUpdates (dict) --
The result configuration information about the queries in this workgroup that will be updated. Includes the updated results location and an updated option for encrypting query results.
OutputLocation (string) --
The location in Amazon S3 where your query results are stored, such as s3://path/to/query/bucket/ . For more information, see Query Results If workgroup settings override client-side settings, then the query uses the location for the query results and the encryption configuration that are specified for the workgroup. The "workgroup settings override" is specified in EnforceWorkGroupConfiguration (true/false) in the WorkGroupConfiguration. See WorkGroupConfiguration$EnforceWorkGroupConfiguration .
RemoveOutputLocation (boolean) --
If set to "true", indicates that the previously-specified query results location (also known as a client-side setting) for queries in this workgroup should be ignored and set to null. If set to "false" or not set, and a value is present in the OutputLocation in ResultConfigurationUpdates (the client-side setting), the OutputLocation in the workgroup's ResultConfiguration will be updated with the new value. For more information, see Workgroup Settings Override Client-Side Settings .
EncryptionConfiguration (dict) --
The encryption configuration for the query results.
EncryptionOption (string) -- [REQUIRED]
Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys (SSE-S3 ), server-side encryption with KMS-managed keys (SSE-KMS ), or client-side encryption with KMS-managed keys (CSE-KMS) is used.
If a query runs in a workgroup and the workgroup overrides client-side settings, then the workgroup's setting for encryption is used. It specifies whether query results must be encrypted, for all queries that run in this workgroup.
KmsKey (string) --
For SSE-KMS and CSE-KMS , this is the KMS key ARN or ID.
RemoveEncryptionConfiguration (boolean) --
If set to "true", indicates that the previously-specified encryption configuration (also known as the client-side setting) for queries in this workgroup should be ignored and set to null. If set to "false" or not set, and a value is present in the EncryptionConfiguration in ResultConfigurationUpdates (the client-side setting), the EncryptionConfiguration in the workgroup's ResultConfiguration will be updated with the new value. For more information, see Workgroup Settings Override Client-Side Settings .
PublishCloudWatchMetricsEnabled (boolean) --
Indicates whether this workgroup enables publishing metrics to Amazon CloudWatch.
BytesScannedCutoffPerQuery (integer) --
The upper limit (cutoff) for the amount of bytes a single query in a workgroup is allowed to scan.
RemoveBytesScannedCutoffPerQuery (boolean) --
Indicates that the data usage control limit per query is removed. WorkGroupConfiguration$BytesScannedCutoffPerQuery
RequesterPaysEnabled (boolean) --
If set to true , allows members assigned to a workgroup to specify Amazon S3 Requester Pays buckets in queries. If set to false , workgroup members cannot query data from Requester Pays buckets, and queries that retrieve data from Requester Pays buckets cause an error. The default is false . For more information about Requester Pays buckets, see Requester Pays Buckets in the Amazon Simple Storage Service Developer Guide .
EngineVersion (dict) --
The engine version requested when a workgroup is updated. After the update, all queries on the workgroup run on the requested engine version. If no value was previously set, the default is Auto. Queries on the AmazonAthenaPreviewFunctionality workgroup run on the preview engine regardless of this setting.
SelectedEngineVersion (string) --
The engine version requested by the user. Possible values are determined by the output of ListEngineVersions , including Auto. The default is Auto.
EffectiveEngineVersion (string) --
Read only. The engine version on which the query runs. If the user requests a valid engine version other than Auto, the effective engine version is the same as the engine version that the user requested. If the user requests Auto, the effective engine version is chosen by Athena. When a request to update the engine version is made by a CreateWorkGroup or UpdateWorkGroup operation, the EffectiveEngineVersion field is ignored.
