[GitHub] [beam] damccorm opened a new issue, #20108: Python direct runner doesn't emit empty pane when it should
damccorm opened a new issue, #20108:
URL: https://github.com/apache/beam/issues/20108
In test_stream_test.py, the test test_gbk_execution_no_triggers there is positive allowed_lateness. So the two windows [15, 30) and [300, 315) that do not have late data should have an empty pane emitted when window finishes (after allowed lateness) since the default ClosingBehavior in Python is EMIT_ALWAYS (see transforms/core.py).

Python direct runner has very limited support for streaming, I wouldn't be surprised if this is still occurring, but I didn't check.

This would be an incorrect result, definitely a real P1. Though in practice users are not relying on this I would guess.
