[jira] [Created] (BEAM-3399) Documentation wrong for Session Windows (Python SDK)

Ralf Hein created BEAM-3399:
-------------------------------

             Summary: Documentation wrong for Session Windows (Python SDK)
                 Key: BEAM-3399
                 URL: https://issues.apache.org/jira/browse/BEAM-3399
             Project: Beam
          Issue Type: Bug
          Components: examples-python
    Affects Versions: 2.2.0
            Reporter: Ralf Hein
            Assignee: Ahmet Altay
            Priority: Minor
             Fix For: Not applicable


The documentation for setting Session Windows via python SDK is wrong (Section 7.3.3).

https://beam.apache.org/documentation/programming-guide/#setting-your-pcollections-windowing-function

It says "time gap of at least 10 minutes" when introducing the example code, but the code actually only sets a duration gap of 10 seconds.

Reason: The duration needs to be passed in seconds, not minutes. So the example code should read something like this:
beam.WindowInto(window.Sessions(10*60)))

Took me quite some time to figure this out ...
