Subject [jira] [Commented] (BEAM-1442) Performance improvement of the Python DirectRunner
Date Fri, 24 Feb 2017 06:45:44 GMT


Haoxiang commented on BEAM-1442:

and when I run python beam sdk in example wordcount, find it can not work on OS X, and the
script ‘’ has some bugs, so I will give an issue to beam and I do not
know if it will influence this project?

>                 Key: BEAM-1442
>                 URL:
>             Project: Beam
>          Issue Type: Improvement
>          Components: sdk-py

> 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 `` and `` methods. Ask questions directly on JIRA.
