.. _auto_keyvalue_value_max:

*COMPUTE THE MAX OF ALL THE VALUES IN THE KEYVALUE*
===================================================

Scans all values in a key-value pair collection and returns the single maximum numeric value. Use this worker whenever you need to extract the largest value across all entries of a keyvalue object within a workflow.

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

Classification: **process**.

Tagged: ``aggregate``, ``keyvalue``, ``max``, ``statistics``, ``transform``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Keyvalue 1
     - kv1
     - keyvalue
     - —
     - 
     - Input key-value collection whose numeric values will be scanned; all entries must be numeric (or coercible to numeric) — leave unconnected if the upstream keyvalue is optional and no max is needed.

Outputs
