-- Modifies the parameters of a DB 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 instance
-- associated with the parameter group before the change can take effect.
--
-- After you modify a DB parameter group, you should wait at least 5
-- minutes before creating your first DB instance that uses that DB
-- parameter group as the default parameter group. This allows Amazon
-- Neptune to fully complete the modify action before the parameter group
-- is used as the default for a new DB instance. This is especially
-- important for parameters that are critical when creating the default
-- database for a DB instance, 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
-- /DescribeDBParameters/ command to verify that your DB parameter group
-- has been created or modified.
