Cache Plugins
-------------

This plugin implelents a backend caching mechanism for Ansible to store gathered facts or inventory source data
to avoid the cost of retrieving them from source.

The default plugin is the :doc:`memory <cache/memory>` plugin which will only cache the data for the current execution of Ansible.
Other plugins with persistent storage are available to allow caching the data across runs.


Enabling Cache Plugins
++++++++++++++++++++++

Only one cache plugin can be active at a time.

You can enable in configuration, either via environment variable:

.. code-block:: shell

    export ANSIBLE_CACHE_PLUGIN=jsonfile

or in the ``ansible.cfg`` file:

.. code-block:: ini

    [defaults]
    fact_caching=redis

You will also need to setup other settings specific to each plugin, you can check the individual plugin documenattion
or the ansible :doc:`configuration <../config>` for more details.

Plugin List
+++++++++++

You can use ``ansible-doc -t cache -l`` to see the list of available plugins,
use ``ansible-doc -t cache <plugin name>`` to see specific documents and examples.
