        # @option arguments [String] :bytes The unit used to display byte values.
        # @option arguments [Boolean, String] :full_id If +true+, return the full node ID. If +false+, return the shortened node ID. Server default: false.
        # @option arguments [Boolean] :include_unloaded_segments If true, the response includes information from segments that are not loaded into memory.
        # @option arguments [String, Array<String>] :h List of columns to appear in the response. Supports simple wildcards.
        # @option arguments [String, Array<String>] :s List of columns that determine how the table should be sorted.
        #  Sorting defaults to ascending and can be changed by setting +:asc+
        #  or +:desc+ as a suffix to the column name.
        # @option arguments [Time] :master_timeout Period to wait for a connection to the master node. Server default: 30s.
        # @option arguments [String] :time Unit used to display time values.
        # @option arguments [String] :format Specifies the format to return the columnar data in, can be set to
