// 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.
// 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 RDS 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 RDS console (https://console.aws.amazon.com/rds/)
// or the DescribeDBParameters command to verify that your DB parameter group has
// been created or modified.
