----------------------------------
Assignee: JingWei Li
> CommonExecTableSourceScan uses physical row type instead of output type for
> upsert source key partitioning
> ------------------------------------------------------------------------------------------------------------
>
> Key: FLINK-39548
> URL: https://issues.apache.org/jira/browse/FLINK-39548
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Reporter: JingWei Li
> Assignee: JingWei Li
> Priority: Major
> Labels: pull-request-available
> Original Estimate: 72h
> Remaining Estimate: 72h
>
> • When CommonExecTableSourceScan wraps an upsert/changelog source with
> configured parallelism, it derives primary-key indices from the
> physical row type.
>
> • If the source output is projected/reordered before the partitioning
> wrapper is created, those indices no longer match the actual output
> schema.
>
> • This causes the generated source partitioning key selector to use wrong
> fields.
