• Engine (string) –

  [REQUIRED]

  The name of the database engine to be used for this cluster.

  The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a cluster using the same Amazon Web Services account that owns the KMS encryption key that is used to encrypt the new cluster, 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 the StorageEncrypted parameter is true, Amazon DocumentDB uses your default encryption key.

  KMS creates the default encryption key for your Amazon Web Services account. Your Amazon Web Services account has a different default encryption key for each Amazon Web Services Regions.

  Not currently supported.

  Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required

• EnableCloudwatchLogsExports (list) –

• GlobalClusterIdentifier (string) – The cluster identifier of the new global cluster.

• StorageType (string) –

  The storage type to associate with the DB cluster.

  For information on storage types for Amazon DocumentDB clusters, see Cluster storage configurations in the Amazon DocumentDB Developer Guide.

  Valid values for storage type - standard | iopt1

  Default value is standard

  Note

  When you create a DocumentDB DB cluster with the storage type set to iopt1, the storage type is returned in the response. The storage type isn’t returned when you set it to standard.

• SourceRegion (string) – The ID of the region that contains the source for the db cluster.

      • (string) –

    • BackupRetentionPeriod (integer) –

      Specifies the number of days for which automatic snapshots are retained.

    • DBClusterIdentifier (string) –

      Contains a user-supplied cluster identifier. This identifier is the unique key that identifies a cluster.

    • DBClusterParameterGroup (string) –

      Specifies the name of the cluster parameter group for the cluster.

    • DBSubnetGroup (string) –

      Specifies information on the subnet group that is associated with the cluster, including the name, description, and subnets in the subnet group.

    • Status (string) –

      Specifies the current state of this cluster.

    • PercentProgress (string) –

      Specifies the progress of the operation as a percentage.

As clients request new connections to the reader endpoint, Amazon DocumentDB distributes the connection requests among the Amazon DocumentDB replicas in the cluster. This functionality can help balance your read workload across multiple Amazon DocumentDB replicas in your cluster.

      If a failover occurs, and the Amazon DocumentDB 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 Amazon DocumentDB replicas in the cluster, you can then reconnect to the reader endpoint.
