> The DirectRunner for Python and Java are intended to act as policy enforcers, and correctness checkers for Beam pipelines; but there are users that run data processing tasks in them.
> Currently, the Python Direct Runner has less-than-great performance, although some work has gone into improving it. There are more opportunities for improvement.
> Skills for this project:
> * Python
> * Cython (nice to have)
> * Working through the Beam getting started materials (nice to have)
> To start figuring out this problem, it is advisable to run a simple pipeline, and study the `Pipeline.run` and `DirectRunner.run` methods. Ask questions directly on JIRA.
