You can set this value only on Aurora DB clusters that are members of an Aurora global database. With this parameter enabled, a secondary cluster can forward writes to the current primary cluster and the resulting changes are replicated back to this cluster. For the primary DB cluster of an Aurora global database, this value is used immediately if the primary is demoted by the FailoverGlobalCluster API operation, but it does nothing until then.

Valid for: Aurora DB clusters only

Shorthand Syntax:

MinCapacity=double,MaxCapacity=double

JSON Syntax:

{
  "MinCapacity": double,
  "MaxCapacity": double
}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To modify a DB cluster

The following modify-db-cluster example changes the master user password for the DB cluster named cluster-2 and sets the backup retention period to 14 days. The --apply-immediately parameter causes the changes to be made immediately, instead of waiting until the next maintenance window.

aws rds modify-db-cluster \
    --db-cluster-identifier cluster-2 \
    --backup-retention-period 14 \
    --master-user-password newpassword99 \

Output¶

DBCluster -> (structure)

Contains the details of an Amazon Aurora DB cluster or Multi-AZ DB cluster.

For an Amazon Aurora DB cluster, this data type is used as a response element in the operations CreateDBCluster , DeleteDBCluster , DescribeDBClusters , FailoverDBCluster , ModifyDBCluster , PromoteReadReplicaDBCluster , RestoreDBClusterFromS3 , RestoreDBClusterFromSnapshot , RestoreDBClusterToPointInTime , StartDBCluster , and StopDBCluster .

For a Multi-AZ DB cluster, this data type is used as a response element in the operations CreateDBCluster , DeleteDBCluster , DescribeDBClusters , FailoverDBCluster , ModifyDBCluster , RebootDBCluster , RestoreDBClusterFromSnapshot , and RestoreDBClusterToPointInTime .

For more information on Amazon Aurora DB clusters, see What is Amazon Aurora? in the Amazon Aurora User Guide.

For more information on Multi-AZ DB clusters, see Multi-AZ deployments with two readable standby DB instances in the Amazon RDS User Guide.

AllocatedStorage -> (integer)

For all database engines except Amazon Aurora, AllocatedStorage specifies the allocated storage size in gibibytes (GiB). For Aurora, AllocatedStorage always returns 1, because Aurora DB cluster storage size isn’t fixed, but instead automatically adjusts as needed.

If present, specifies the name of the character set that this cluster is associated with.

DatabaseName -> (string)

Contains the name of the initial database of this DB cluster that was provided at create time, if one was specified when the DB cluster was created. This same name is returned for the life of the DB cluster.
