        # ==== Parameters
        #
        # @param [Hash] options
        # * :cluster_parameter_group_family - (String)
        #    The name of a specific cluster parameter group family to return details for.
        #    Constraints: Must be 1 to 255 alphanumeric characters. First character must be
        #    a letter, and cannot end with a hyphen or contain two consecutive hyphens.
        # * :cluster_version - (String)
        #    The specific cluster version to return. Example: 1.0
        # * :max_records - (Integer)
        #    The maximum number of records to include in the response. If more than the
        #    MaxRecords value is available, a marker is included in the response so that the
        #    following results can be retrieved. Constrained between [20,100]. Default is 100.
        # * :marker - (String)
        #    The marker returned from a previous request. If this parameter is specified, the
        #    response includes records beyond the marker only, up to MaxRecords.
