-------------------------------
Summary: State cache clean up doesn't work as expected
Key: FLINK-27108
URL: https://issues.apache.org/jira/browse/FLINK-27108
Project: Flink
Issue Type: Bug
Components: API / Python
Affects Versions: 1.14.0, 1.13.0, 1.15.0
Reporter: Dian Fu
Assignee: Dian Fu
Fix For: 1.15.0, 1.13.7, 1.14.5
The test case test_session_window_late_merge failed when working on
FLINK-26190. After digging into this problem, the reason should be that the
logic to determine [whether a key & namespace exists in state cache is
wrong|https://github.com/apache/flink/blob/master/flink-python/pyflink/fn_execution/state_impl.py#L1183]
is wrong. It causes the state cache isn't clean up when it becomes invalidate.
