These tasks can be anything, but are typically long running things like jobs, dumping data to/from databases, running machine learning algorithms, or anything else. There are other software packages that focus on lower level aspects of data processing, like,,. Luigi is not a framework to replace these. Instead it helps you stitch many tasks together, where each task can be a, a, a, a Python snippet, from a database, or anything else.

It's easy to build up long-running pipelines that comprise thousands of tasks and take days or weeks to complete.

Everything in Luigi is in Python.

Instead of XML configuration or similar external data files, the dependency graph is specified within Python. This makes it easy to build up complex dependency graphs of tasks, where the dependencies can involve date algebra or recursive references to other versions of the same task. However, the workflow can trigger things not in Python, such as running. Who uses Luigi?

We use Luigi internally at to run thousands of tasks every day, organized in complex dependency graphs. Most of these tasks are Hadoop jobs.
