[jira] [Created] (BEAM-8532) Beam Python trigger driver sets incorrect timestamp for output windows.

Robert Bradshaw created BEAM-8532:
-------------------------------------

             Summary: Beam Python trigger driver sets incorrect timestamp for output windows.
                 Key: BEAM-8532
                 URL: https://issues.apache.org/jira/browse/BEAM-8532
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Robert Bradshaw
            Assignee: Robert Bradshaw


The timestamp should lie in the window, otherwise re-windowing will not be idempotent. 

https://github.com/apache/beam/blob/release-2.16.0/sdks/python/apache_beam/transforms/trigger.py#L1183 should be using {{window.max_timestamp()}} rather than {{.end}}
