type DBClusterIdentifier:

string

param DBClusterIdentifier:

[REQUIRED]

The DB cluster identifier for the cluster being modified. This parameter is not case-sensitive.

Constraints: This identifier must match the identifier of an existing DB cluster.

type NewDBClusterIdentifier:

string

param NewDBClusterIdentifier:

The new DB cluster identifier for the DB cluster when renaming a DB cluster. This value is stored as a lowercase string.

Constraints:

  • Must contain from 1 to 63 letters, numbers, or hyphens

  • The first character must be a letter

  • Can't end with a hyphen or contain two consecutive hyphens

Example: my-cluster2

type ApplyImmediately:

boolean

param ApplyImmediately:

A value that indicates whether the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the PreferredMaintenanceWindow setting for the DB cluster. If this parameter is disabled, changes to the DB cluster are applied during the next maintenance window.

The ApplyImmediately parameter only affects the EnableIAMDatabaseAuthentication, MasterUserPassword, and NewDBClusterIdentifier values. If the ApplyImmediately parameter is disabled, then changes to the EnableIAMDatabaseAuthentication, MasterUserPassword, and NewDBClusterIdentifier values are applied during the next maintenance window. All other changes are applied immediately, regardless of the value of the ApplyImmediately parameter.

By default, this parameter is disabled.

type BackupRetentionPeriod:

integer

param BackupRetentionPeriod:

The number of days for which automated backups are retained. You must specify a minimum value of 1.

Default: 1

Constraints:

  • Must be a value from 1 to 35

type DBClusterParameterGroupName:

string

param DBClusterParameterGroupName:

The name of the DB cluster parameter group to use for the DB cluster.

type VpcSecurityGroupIds:

list

param VpcSecurityGroupIds:

A list of VPC security groups that the DB cluster will belong to.

  • (string) --

integer

param Port:

The port number on which the DB cluster accepts connections.

Constraints: Value must be 1150-65535

Default: The same port as the original DB cluster.

Constraints: Must contain from 8 to 41 characters.

type OptionGroupName:

string

param OptionGroupName:

A value that indicates that the DB cluster should be associated with the specified option group. Changing this parameter doesn't result in an outage except in the following case, and the change is applied during the next maintenance window unless the ApplyImmediately is enabled for this request. If the parameter change results in an option group that enables OEM, this change can cause a brief (sub-second) period during which new connections are rejected but existing connections are not interrupted.

Permanent options can't be removed from an option group. The option group can't be removed from a DB cluster once it is associated with a DB cluster.

type PreferredBackupWindow:

Response Structure

  • (dict) --

    • DBCluster (dict) --

      Contains the details of an Amazon Aurora DB cluster.

      This data type is used as a response element in the DescribeDBClusters, StopDBCluster, and StartDBCluster actions.

      • 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 is not fixed, but instead automatically adjusts as needed.

      • AvailabilityZones (list) --

        Provides the list of Availability Zones (AZs) where instances in the DB cluster can be created.

        • (string) --

      • BackupRetentionPeriod (integer) --

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

      • CharacterSetName (string) --

        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.

      • DBClusterIdentifier (string) --

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

      • DBClusterParameterGroup (string) --

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

      • DBSubnetGroup (string) --

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

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

        If a failover occurs, and the Aurora 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 Aurora Replicas in the cluster, you can then reconnect to the reader endpoint.

      • AssociatedRoles (list) --

        Provides a list of the AWS Identity and Access Management (IAM) roles that are associated with the DB cluster. IAM roles that are associated with a DB cluster grant permission for the DB cluster to access other AWS services on your behalf.
