<p>Dynflow (<strong>DYN</strong>amic work<strong>FLOW</strong>) is a workflow engine
written in Ruby that allows to:</p>
<ul>
<li> Keep track of the progress of running processes</li>
<li> Run the code asynchronously</li>
<li> When something goes wrong, pause the process, optionally let user interact,
resume the process, skip some steps when needed</li>
<li> Detect independent parts and run them concurrently</li>
<li> Compose simple actions into more complex scenarios</li>
<li> Extend the workflows from third-party libraries</li>
<li> Keep consistency between local transactional database and
external services</li>
<li> Suspend the long-running steps, not blocking the thread pool</li>
<li> Cancel steps when possible</li>
<li> Extend the actions behavior with middlewares</li>
<li> Pick different adapters to provide: storage backend, transactions, or executor implementation</li>
</ul>
<p>Dynflow has been developed to be able to support orchestration of services in the
<a href="http://katello.org">Katello</a> and <a href="http://theforeman.org/">Foreman</a> projects.</p>
<h3 id="planned-features">Planned features</h3>
<ul>
<li> Define the input/output interface between the building blocks</li>
<li> Define rollback for the workflow</li>
<li> Have multiple workers for distributing the load (in progress)</li>
<li> Migration to <a href="http://concurrent-ruby.com">concurrent-ruby</a> (in progress)</li>
</ul>
<h2 id="getting-started">Getting started</h2>
<h3 id="requirements">Requirements</h3>
<ul>
<li> Ruby MRI 1.9.3, 2.0, or 2.1.</li>
<li> JRuby and Rubinius support is on the way.</li>
