  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.

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.

Request

• DBClusterIdentifier  (in the CLI: --db-cluster-identifier,  or in Python: db_cluster_identifier) – UTF-8 string.

  A DB cluster identifier to force a failover for. This parameter is not case-sensitive.

• IAMDatabaseAuthenticationEnabled  (in the CLI: --iam-database-authentication-enabled,  or in Python: iam_database_authentication_enabled) – Boolean.

  True if mapping of Amazon Identity and Access Management (IAM) accounts to database accounts is enabled, and otherwise false.

• KmsKeyId  (in the CLI: --kms-key-id,  or in Python: kms_key_id) – UTF-8 string.

  If StorageEncrypted is true, the Amazon KMS key identifier for the encrypted DB cluster.

• LatestRestorableTime  (in the CLI: --latest-restorable-time,  or in Python: latest_restorable_time) – Timestamp.

  Specifies the latest time to which a database can be restored with point-in-time restore.

• MultiAZ  (in the CLI: --multi-az,  or in Python: multi_az) – Boolean.

  Specifies whether the DB cluster has instances in multiple Availability Zones.

• PendingModifiedValues  (in the CLI: --pending-modified-values,  or in Python: pending_modified_values) – A ClusterPendingModifiedValues object.

  Not supported by Neptune.

• PercentProgress  (in the CLI: --percent-progress,  or in Python: percent_progress) – UTF-8 string.

  Specifies the progress of the operation as a percentage.

• Port  (in the CLI: --port,  or in Python: port) – Number (integer).

  Specifies the port that the database engine is listening on.

• PreferredBackupWindow  (in the CLI: --preferred-backup-window,  or in Python: preferred_backup_window) – UTF-8 string.

  Specifies the daily time range during which automated backups are created if automated backups are enabled, as determined by the BackupRetentionPeriod.

• PreferredMaintenanceWindow  (in the CLI: --preferred-maintenance-window,  or in Python: preferred_maintenance_window) – UTF-8 string.

  Specifies the weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).

• ReaderEndpoint  (in the CLI: --reader-endpoint,  or in Python: reader_endpoint) – UTF-8 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.

• ReadReplicaIdentifiers  (in the CLI: --read-replica-identifiers,  or in Python: read_replica_identifiers) – An array of ReadReplicaIdentifier— UTF-8 strings.

  Contains one or more identifiers of the Read Replicas associated with this DB cluster.

• ReplicationSourceIdentifier  (in the CLI: --replication-source-identifier,  or in Python: replication_source_identifier) – UTF-8 string.

  Not supported by Neptune.

• ReplicationType  (in the CLI: --replication-type,  or in Python: replication_type) – UTF-8 string.

  Not supported by Neptune.

• Status  (in the CLI: --status,  or in Python: status) – UTF-8 string.

  Specifies the current state of this DB cluster.

• StorageEncrypted  (in the CLI: --storage-encrypted,  or in Python: storage_encrypted) – Boolean.

  Specifies whether the DB cluster is encrypted.

• VpcSecurityGroups  (in the CLI: --vpc-security-groups,  or in Python: vpc_security_groups) – An array of VpcSecurityGroupMembership VpcSecurityGroupMembership objects.

  Provides a list of VPC security groups that the DB cluster belongs to.

Errors

• DBClusterNotFoundFault

• InvalidDBClusterStateFault

DescribeDBClusters (action)

        The Amazon CLI name for this API is: describe-db-clusters,  and the Python name is: describe_db_clusters.

Returns information about provisioned DB clusters, and supports pagination.

Note

This operation can also return information for Amazon RDS clusters and Amazon DocDB clusters.

Request

• DBClusterIdentifier  (in the CLI: --db-cluster-identifier,  or in Python: db_cluster_identifier) – UTF-8 string.

  The user-supplied DB cluster identifier. If this parameter is specified, information from only the specific DB cluster is returned. This parameter isn't case-sensitive.

  Constraints:

  • If supplied, must match an existing DBClusterIdentifier.

• Filters  (in the CLI: --filters,  or in Python: filters) – An array of Filter Filter objects.

  A filter that specifies one or more DB clusters to describe.

  Supported filters:

  • db-cluster-id - Accepts DB cluster identifiers and DB cluster Amazon Resource Names (ARNs). The results list will only include information about the DB clusters identified by these ARNs.

  • engine - Accepts an engine name (such as neptune), and restricts the results list to DB clusters created by that engine.

  For example, to invoke this API from the Amazon CLI and filter so that only Neptune DB clusters are returned, you could use the following command:

  aws neptune describe-db-clusters \
              --filters  Name=engine,Values=neptune

• Marker  (in the CLI: --marker,  or in Python: marker) – UTF-8 string.

  An optional pagination token provided by a previous DescribeDBClusters (action) request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

• MaxRecords  (in the CLI: --max-records,  or in Python: max_records) – Number (integer).

  The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a pagination token called a marker is included in the response so that the remaining results can be retrieved.

  Default: 100

  Constraints: Minimum 20, maximum 100.

Response

• DBClusters  (in the CLI: --db-clusters,  or in Python: db_clusters) – An array of DBCluster DBCluster objects.

  Contains a list of DB clusters for the user.

• Marker  (in the CLI: --marker,  or in Python: marker) – UTF-8 string.

  A pagination token that can be used in a subsequent DescribeDBClusters request.

Errors

• DBClusterNotFoundFault
