.. _auto_keyvalue_sort:

*RETURN THE UNIQUE KEY VALUES FROM THE GIVEN RESPONSE*
======================================================

Extracts unique key values from a key-value response and returns them in a specified sort order. Use this worker to deduplicate and rank key-value entries when a sorted, optionally truncated list of unique keys is needed downstream.

When to use
-----------

Classification: **process**.

Tagged: ``dedup``, ``keyvalue``, ``process``, ``sort``, ``transform``, ``unique``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Response
     - response
     - keyvalue
     - —
     - 
     - Key-value response object to process; supply any key-value input whose unique keys are to be extracted and sorted.
   * - Sort Type
     - sort_type
     - scalar
     - asc
     - 
     - Sort direction for the returned unique keys — 'asc' (ascending, default) or 'desc' (descending).
   * - Limit
     - limit
     - scalar
     - -1
     - 
     - Maximum number of unique key values to return; defaults to -1, which returns all unique keys without restriction.

Outputs
-------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20

   * - Label
     - ID
     - Type
     - Description
   * - keyvalue_sort_output_1
     - keyvalue_sort_output_1
     - keyvalue
     - Key-value object containing the deduplicated, sorted (and optionally truncated) unique keys from the input response.
