Workflows
=========

Cirrus workflows are the component that puts the "pipe" in "pipeline".
Workflows model a transformation of an input item or set of input items with a
process definition into one or more output items via processing from one or
more tasks.

Cirrus also provides several mechanisms for modeling workflow dependencies.

The :doc:`state database <../../70_statedb>` tracks the state of items processed at
the workflow level.
