Strategies
===========
In 2.0 we added a new way to control play execution, ``strategy``, by default plays will
still run as they used to, with what we call the ``linear`` strategy. All hosts will run each
task before any host starts the next task, using the number of forks (default 5) to parallelize.
The ``serial`` directive can 'batch' this behaviour to a subset of the hosts, which then run to
completion of the play before the next 'batch' starts.
A second ``strategy`` ships with ansible ``free``, which allows each host to run until the end of
the play as fast as it can.::
- hosts: all
strategy: free
tasks:
...
.. _strategy_plugins:
Strategy Plugins
`````````````````
The strategies are implemented via a new type of plugin, this means that in the future new
execution types can be added, either locally by users or to Ansible itself by
a code contribution.
One example is ``debug`` strategy. See :doc:`playbooks_debugger` for details.
