Container for the parameters to the ModifyDBClusterParameterGroup operation. Modifies the parameters of a DB cluster parameter group. To modify more than one parameter, submit a list of the following: ParameterName, ParameterValue, and ApplyMethod. A maximum of 20 parameters can be modified in a single request.

After you create a DB cluster parameter group, you should wait at least 5 minutes before creating your first DB cluster that uses that DB cluster parameter group as the default parameter group. This allows Amazon RDS to fully complete the create operation before the parameter group is used as the default for a new DB cluster. This is especially important for parameters that are critical when creating the default database for a DB cluster, such as the character set for the default database defined by the character_set_database parameter. You can use the Parameter Groups option of the Amazon RDS console or the DescribeDBClusterParameters operation to verify that your DB cluster parameter group has been created or modified.

If the modified DB cluster parameter group is used by an Aurora Serverless v1 cluster, Aurora applies the update immediately. The cluster restart might interrupt your workload. In that case, your application must reopen any connections and retry any transactions that were active when the parameter changes took effect.

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 DB cluster deployments in the Amazon RDS User Guide.

Properties

NameTypeDescription
Public Property DBClusterParameterGroupName System.String

Gets and sets the property DBClusterParameterGroupName.

The name of the DB cluster parameter group to modify.

Public Property Parameters System.Collections.Generic.List<Amazon.RDS.Model.Parameter>

Gets and sets the property Parameters.

A list of parameters in the DB cluster parameter group to modify.

Valid Values (for the application method): immediate | pending-reboot

You can use the immediate value with dynamic parameters only. You can use the pending-reboot value for both dynamic and static parameters.

When the application method is immediate, changes to dynamic parameters are applied immediately to the DB clusters associated with the parameter group. When the application method is pending-reboot, changes to dynamic and static parameters are applied after a reboot without failover to the DB clusters associated with the parameter group.
