/#Action=ModifyDBClusterParameterGroup

http://rds.{region}.amazonaws.com/#Action=ModifyDBClusterParameterGroup

Modifies the parameters of a DB cluster parameter group. To modify more than one parameter, submit a list of the following: <code>ParameterName</code>, <code>ParameterValue</code>, and <code>ApplyMethod</code>. A maximum of 20 parameters can be modified in a single request. <important> 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 action 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 <code>character_set_database</code> parameter. You can use the Parameter Groups option of the <a href="https://console.aws.amazon.com/rds/">Amazon RDS console</a> or the <code>DescribeDBClusterParameters</code> 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. </important> For more information on Amazon Aurora DB clusters, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/CHAP_AuroraOverview.html"> What is Amazon Aurora?</a> in the Amazon Aurora User Guide. For more information on Multi-AZ DB clusters, see <a href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/multi-az-db-clusters-concepts.html"> Multi-AZ DB cluster deployments</a> in the Amazon RDS User Guide.

Query Params

DBClusterParameterGroupNamestringrequired

The name of the DB cluster parameter group to modify.

Parametersarrayrequired

A list of parameters in the DB cluster parameter group to modify. Valid Values (for the application method): <code>immediate | pending-reboot</code> <note> You can use the <code>immediate</code> value with dynamic parameters only. You can use the <code>pending-reboot</code> value for both dynamic and static parameters. When the application method is <code>immediate</code>, changes to dynamic parameters are applied immediately to the DB clusters associated with the parameter group. When the application method is <code>pending-reboot</code>, changes to dynamic and static parameters are applied after a reboot without failover to the DB clusters associated with the parameter group. </note>
