// 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.
