    :param CacheParameterGroupFamily: [REQUIRED]
            The name of the cache parameter group family.
            Valid values are: memcached1.4 | redis2.6 | redis2.8 | redis3.2
            

    :type MaxRecords: integer
    :param MaxRecords: The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a marker is included in the response so that the remaining results can be retrieved.
            Default: 100
            Constraints: minimum 20; maximum 100.
            

    :type Marker: string
    :param Marker: An optional marker returned from a prior request. Use this marker for pagination of results from this operation. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords .
