Automated database cache cleanup
--------------------------------

.. _20.1.1|VOSS-703:


From Automate release 19.3.2 onwards, it is now longer necessary to schedule or manually
manage the database cache optimization using the ``voss trim-cache`` command. 

From release 20.1.1, this command is no longer available. A resource history is now maintained
as a series of resource differences and is automatically optimized.

.. note::
  
   A minimum retention period of seven (7) days is applied to resource differences in the resource history.
