2022/10/26 - Amazon Neptune - 10 updated api methods
Changes Added a new cluster-level attribute to set the capacity range for Neptune Serverless instances.
{'ServerlessV2ScalingConfiguration': {'MaxCapacity': 'double',
'MinCapacity': 'double'}}
Response {'DBCluster': {'ServerlessV2ScalingConfiguration': {'MaxCapacity': 'double',
'MinCapacity': 'double'}}}
Creates a new Amazon Neptune DB cluster.
You can use the ReplicationSourceIdentifier parameter to create the DB cluster as a Read Replica of another DB cluster or Amazon Neptune DB instance.
Note that when you create a new cluster using CreateDBCluster directly, deletion protection is disabled by default (when you create a new production cluster in the console, deletion protection is enabled by default). You can only delete a DB cluster if its DeletionProtection field is set to false .

string
The Amazon Resource Name (ARN) of the source DB instance or DB cluster if this DB cluster is created as a Read Replica.
list
The tags to assign to the new DB cluster.
(dict) --
Metadata assigned to an Amazon Neptune resource consisting of a key-value pair.
Key (string) --
A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can't be prefixed with aws: or rds: . The string can only contain the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").

boolean
Specifies whether the DB cluster is encrypted.
string
The Amazon KMS key identifier for an encrypted DB cluster.
The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a DB cluster with the same Amazon account that owns the KMS encryption key used to encrypt the new DB cluster, then you can use the KMS key alias instead of the ARN for the KMS encryption key.
If an encryption key is not specified in KmsKeyId :
If ReplicationSourceIdentifier identifies an encrypted source, then Amazon Neptune will use the encryption key used to encrypt the source. Otherwise, Amazon Neptune will use your default encryption key.
If the StorageEncrypted parameter is true and ReplicationSourceIdentifier is not specified, then Amazon Neptune will use your default encryption key.
Amazon KMS creates the default encryption key for your Amazon account. Your Amazon account has a different default encryption key for each Amazon Region.
If you create a Read Replica of an encrypted DB cluster in another Amazon Region, you must set KmsKeyId to a KMS key ID that is valid in the destination Amazon Region. This key is used to encrypt the Read Replica in that Amazon Region.

{'DBCluster': {'ServerlessV2ScalingConfiguration': {'MaxCapacity': 'double',
'MinCapacity': 'double'}}}
Forces a failover for a DB cluster.
A failover for a DB cluster promotes one of the Read Replicas (read-only instances) in the DB cluster to be the primary instance (the cluster writer).
Amazon Neptune will automatically fail over to a Read Replica, if one exists, when the primary instance fails. You can force a failover when you want to simulate a failure of a primary instance for testing. Because each instance in a DB cluster has its own endpoint address, you will need to clean up and re-establish any existing connections that use those endpoint addresses when the failover is complete.

If a failover occurs, and the Read Replica that you are connected to is promoted to be the primary instance, your connection is dropped. To continue sending your read workload to other Read Replicas in the cluster, you can then reconnect to the reader endpoint.

Response {'DBCluster': {'ServerlessV2ScalingConfiguration': {'MaxCapacity': 'double',
'MinCapacity': 'double'}}}
Restores a DB cluster to an arbitrary point in time. Users can restore to any point in time before LatestRestorableTime for up to BackupRetentionPeriod days. The target DB cluster is created from the source DB cluster with the same configuration as the original DB cluster, except that the new DB cluster is created with the default DB security group.
Note
This action only restores the DB cluster, not the DB instances for that DB cluster. You must invoke the CreateDBInstance action to create DB instances for the restored DB cluster, specifying the identifier of the restored DB cluster in DBClusterIdentifier . You can create DB instances only after the RestoreDBClusterToPointInTime action has completed and the DB cluster is available.

string
[REQUIRED]
The name of the new DB cluster to be created.
Constraints:
Must contain from 1 to 63 letters, numbers, or hyphens
First character must be a letter
Cannot end with a hyphen or contain two consecutive hyphens
string
The type of restore to be performed. You can specify one of the following values:
full-copy - The new DB cluster is restored as a full copy of the source DB cluster.
copy-on-write - The new DB cluster is restored as a clone of the source DB cluster.
If you don't specify a RestoreType value, then the new DB cluster is restored as a full copy of the source DB cluster.
string
[REQUIRED]
The identifier of the source DB cluster from which to restore.
Constraints:
Must match the identifier of an existing DBCluster.
datetime
The date and time to restore the DB cluster to.
Valid Values: Value must be a time in Universal Coordinated Time (UTC) format
Constraints:
Must be before the latest restorable time for the DB instance
Must be specified if UseLatestRestorableTime parameter is not provided
Cannot be specified if UseLatestRestorableTime parameter is true
Cannot be specified if RestoreType parameter is copy-on-write
Example: 2015-03-07T23:45:00Z
boolean
A value that is set to true to restore the DB cluster to the latest restorable backup time, and false otherwise.
Default: false
Constraints: Cannot be specified if RestoreToTime parameter is provided.
integer
The port number on which the new DB cluster accepts connections.
Constraints: Value must be 1150-65535
Default: The same port as the original DB cluster.
string

Constraints: If supplied, must match the name of an existing DBSubnetGroup.
Example: mySubnetgroup
string
(Not supported by Neptune)
list
A list of VPC security groups that the new DB cluster belongs to.
(string) --
list
The tags to be applied to the restored DB cluster.
(dict) --
Metadata assigned to an Amazon Neptune resource consisting of a key-value pair.
Key (string) --
A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can't be prefixed with aws: or rds: . The string can only contain the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
Value (string) --
A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and can't be prefixed with aws: or rds: . The string can only contain the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
string
The Amazon KMS key identifier to use when restoring an encrypted DB cluster from an encrypted DB cluster.
The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are restoring a DB cluster with the same Amazon account that owns the KMS encryption key used to encrypt the new DB cluster, then you can use the KMS key alias instead of the ARN for the KMS encryption key.
You can restore to a new DB cluster and encrypt the new DB cluster with a KMS key that is different than the KMS key used to encrypt the source DB cluster. The new DB cluster is encrypted with the KMS key identified by the KmsKeyId parameter.
If you do not specify a value for the KmsKeyId parameter, then the following will occur:
If the DB cluster is encrypted, then the restored DB cluster is encrypted using the KMS key that was used to encrypt the source DB cluster.
If the DB cluster is not encrypted, then the restored DB cluster is not encrypted.
If DBClusterIdentifier refers to a DB cluster that is not encrypted, then the restore request is rejected.
boolean
True to enable mapping of Amazon Identity and Access Management (IAM) accounts to database accounts, and otherwise false.
Default: false
list
The list of logs that the restored DB cluster is to export to CloudWatch Logs.
(string) --
string

Specifies the earliest time to which a database can be restored with point-in-time restore.
Endpoint (string) --
Specifies the connection endpoint for the primary instance of the DB cluster.
ReaderEndpoint (string) --
The reader endpoint for the DB cluster. The reader endpoint for a DB cluster load-balances connections across the Read Replicas that are available in a DB cluster. As clients request new connections to the reader endpoint, Neptune distributes the connection requests among the Read Replicas in the DB cluster. This functionality can help balance your read workload across multiple Read Replicas in your DB cluster.
If a failover occurs, and the Read Replica that you are connected to is promoted to be the primary instance, your connection is dropped. To continue sending your read workload to other Read Replicas in the cluster, you can then reconnect to the reader endpoint.
