-- 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.

--
-- /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 @character_set_database@ parameter. You can use the /Parameter Groups/ option of the <https://console.aws.amazon.com/rds/ Amazon RDS console> or the 'DescribeDBClusterParameters' command to verify that your DB cluster parameter group has been created or modified.
