----------------------------------------
Summary: LTS backport: FlinkRunner does not checkpoint partition
view of watermark holds
Key: BEAM-7188
URL: https://issues.apache.org/jira/browse/BEAM-7188
Project: Beam
Issue Type: Bug
Components: runner-flink
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: 2.11.0
The FlinkRunner does not persist its view of the per-partition Watermark holds.
This can lead to elements to be considered late after restoring from a
savepoint or resuming a failed pipeline.
Similar to the approach in BEAM-6650, we can recover the Watermarks by
iterating through the keys of the state backend during recovery.
