Ahmet Altay commented on BEAM-1442: ----------------------------------- Have you tried running wordcount locally on OS X? That should work, and it is also part of our regular test matrix. run_postcommit is meant to run as part of the integration tests and not by developers directly. It runs wordcount locally then with Dataflow service, it is a paid service and requires account/project etc. creation. You are probably seeing errors related to the second part. > Performance improvement of the Python DirectRunner > -------------------------------------------------- > > Key: BEAM-1442 > URL: https://issues.apache.org/jira/browse/BEAM-1442 > Project: Beam > Issue Type: Improvement > Components: sdk-py > Reporter: Pablo Estrada > Assignee: Ahmet Altay > Labels: gsoc2017, mentor, python > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
