Ankur Goenka updated BEAM-3189: ------------------------------- External issue URL: https://docs.google.com/document/d/1mHFaNgHA71RVGLVNrGrHIlWHgJb4tKCJ2qQzS13REY8 > Python Fnapi - Worker speedup > ----------------------------- > > Key: BEAM-3189 > URL: https://issues.apache.org/jira/browse/BEAM-3189 > Project: Beam > Issue Type: Improvement > Components: sdk-py-harness > Affects Versions: 2.3.0 > Reporter: Ankur Goenka > Assignee: Ankur Goenka > Priority: Minor > Labels: performance, portability > > Beam Python SDK is couple of magnitude slower than Java SDK when it comes to > stream processing. > There are two related issues: > # Given a single core, currently we are not fully utilizing the core because > the single thread spends a lot of time on the IO. This is more of a > limitation of our implementation rather than a limitation of Python. > # Given a machine with multiple cores, single Python process could only > utilize one core. > In this task we will only address 1. 2 will be good for future optimization. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
