-- 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.
--
-- For more information on Amazon Aurora, see
-- <http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Aurora.html Aurora on Amazon RDS>
-- in the /Amazon RDS User Guide./
--
-- Changes to dynamic parameters are applied immediately. Changes to static
-- parameters require a reboot without failover to the DB cluster
-- associated with the parameter group before the change can take effect.
--
-- 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.
