Luigi: complex pipelines of tasks in Python

I’m shamelessly promoting my first major open source project. Luigi is a Python module that helps you build complex pipelines of batch jobs, handle dependency resolution, and create visualizations to help manage multiple workflows. It also comes with Hadoop support built in (because that’s where really where its strength becomes clear).

We use Luigi internally at Spotify to run thousands of tasks every day, organized in complex dependency graphs. Luigi provides an infrastructure that powers several Spotify features including recommendations, top lists, A/B test analysis, external reports, internal dashboards, and many more.

Conceptually, Luigi is similar to GNU Make where you have certain tasks and these tasks in turn may have dependencies on other tasks.
