.. _auto_keyvalue_merge:

*MERGE TWO KEYVALUES*
=====================

Merges two key-value maps into a single combined key-value output. Keys from the second map (Keyvalue to Merge) take precedence over matching keys in the base map. Use this worker to consolidate or override configuration parameters within a workflow.

When to use

Classification: **process**.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Keyvalue Base
     - keyvalue_base
     - keyvalue
     - —
     - 
     - The base key-value map that provides the starting set of key-value pairs; entries here may be overridden by matching keys in the merge input. Leave empty if there is no base context.
   * - Keyvalue To Merge
     - keyvalueto_mege
     - keyvalue
     - —
     - 
     - The key-value map to merge into the base; keys present in both maps will use the value from this input, effectively acting as an override or patch layer.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - keyvalue_merge_output_1
     - keyvalue_merge_output_1
     - keyvalue
     - The resulting merged key-value map containing all keys from both inputs, with values from 'Keyvalue to Merge' taking precedence where keys conflict.
