// 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 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 character_set_database parameter. You
// can use the Parameter Groups option of the Amazon RDS console
// (https://console.aws.amazon.com/rds/) 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?
// (https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/CHAP_AuroraOverview.html)
// in the Amazon Aurora User Guide. For more information on Multi-AZ DB clusters,
// see  Multi-AZ deployments with two readable standby DB instances
// (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/multi-az-db-clusters-concepts.html)
// in the Amazon RDS User Guide.
