---------------------------------
Summary: PyFlink WindowOperator#process_element register wrong
cleanup timer
Key: FLINK-26775
URL: https://issues.apache.org/jira/browse/FLINK-26775
Project: Flink
Issue Type: Bug
Components: API / Python
Affects Versions: 1.15.0
Reporter: Juntao Hu
Fix For: 1.15.0
In window_operator.py line 378, when dealing with merging window assigner:
{code:python}
self.register_cleanup_timer(window)
{code}
This should be registering a cleanup timer for `actual_window`, but won't
causing window emitting bugs when session window trigger is implemented
correctly.
