        # ==== Parameters
        #
        # @param [Hash] options
        # * :parameter_group_name - required - (String)
        #    The name of the cluster parameter group. Constraints: Must be 1 to 255 alphanumeric
        #    characters or hyphens First character must be a letter. Cannot end with a hyphen or
        #    contain two consecutive hyphens. Must be unique within your AWS account. This value
        #    is stored as a lower-case string.
        # * :parameter_group_family - required - (String)
        #    The Amazon Redshift engine version to which the cluster parameter group applies. The
        #    cluster engine version determines the set of parameters. To get a list of valid parameter
        #    group family names, you can call DescribeClusterParameterGroups. By default, Amazon
        #    Redshift returns a list of all the parameter groups that are owned by your AWS account,
        #    including the default parameter groups for each Amazon Redshift engine version. The
        #    parameter group family names associated with the default parameter groups provide you
        #    the valid values. For example, a valid family name is "redshift-1.0".
        # * :description - required - (String)
        #    A description of the parameter group.
        #
