-- 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.
--
-- 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 Neptune 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 Neptune console or the
-- DescribeDBClusterParameters command to verify that your DB cluster
-- parameter group has been created or modified.
