Working with Actions
====================

An action is an abstraction of some logic that can be executed by a worker
thread. Most of the operations supported by Senlin are executed asynchronously,
which means they are queued into database and then picked up by certain worker
thread for execution.


List Actions
~~~~~~~~~~~~

To examine the list of actions:

.. literalinclude:: ../../examples/clustering/action.py
   :pyobject: list_actions

When listing actions, you can specify the sorting option using the ``sort``
parameter and you can do pagination using the ``limit`` and ``marker``
parameters.

Full example: `manage action`_


Get Action
~~~~~~~~~~

To get a action based on its name or ID:

.. literalinclude:: ../../examples/clustering/action.py
   :pyobject: get_action

.. _manage action: http://git.openstack.org/cgit/openstack/openstacksdk/tree/examples/clustering/action.py
