Cache Plugins
-------------
Cache plugin implement a backend caching mechanism that allows Ansible to store gathered facts or inventory source data
without the performance hit of retrieving them from source.
The default cache plugin is the :doc: `memory <cache/memory>` plugin, which only caches the data for the current execution of Ansible. Other plugins with persistent storage are available to allow caching the data across runs.
.. _enabling_cache:
Enabling Cache Plugins
++++++++++++++++++++++
Only one cache plugin can be active at a time.
You can enable a cache plugin in the Ansible 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 configure other settings specific to each plugin. Consult the individual plugin documentation
or the Ansible :ref: `configuration <ansible_configuration_settings>` for more details.
A custom cache plugin is enabled by dropping it into a `` cache_plugins `` directory adjacent to your play, inside a role, or by putting it in one of the directory sources configured in :ref: `ansible.cfg <ansible_configuration_settings>` .
.. _using_cache:
Using Cache Plugins
+++++++++++++++++++
Cache plugins are used automatically once they are enabled.
.. _cache_plugin_list:
