-- | Creates a value of 'DescribeDBClusterParameterGroups' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'ddcpgFilters' - This parameter is not currently supported.
--
-- * 'ddcpgMarker' - An optional pagination token provided by a previous @DescribeDBClusterParameterGroups@ request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by @MaxRecords@ .
--
-- * 'ddcpgMaxRecords' - The maximum number of records to include in the response. If more records exist than the specified @MaxRecords@ value, a pagination token called a marker is included in the response so that the remaining results can be retrieved.  Default: 100 Constraints: Minimum 20, maximum 100.
--
-- * 'ddcpgDBClusterParameterGroupName' - The name of a specific DB cluster parameter group to return details for. Constraints:     * Must be 1 to 255 alphanumeric characters     * First character must be a letter     * Cannot end with a hyphen or contain two consecutive hyphens
