------------------------------------
Assignee: Nicholas Chew
> Fix time window join in stream-stream join state format V4
> ----------------------------------------------------------
>
> Key: SPARK-55987
> URL: https://issues.apache.org/jira/browse/SPARK-55987
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 4.2.0
> Reporter: Nicholas Chew
> Assignee: Nicholas Chew
> Priority: Major
> Labels: pull-request-available
>
> Stream-stream join V4 state manager was deducing the event time column
> ordinal in join keys independently per side which didn't work for window
> structs.
> Instead, use findJoinKeyOrdinalForWatermark from
> StreamingSymmetricHashJoinHelper which correctly resolves this for both sides.
