Luka Zdravic resolved SPARK-59298.
----------------------------------
Resolution: Resolved
> ASOF JOIN production-readiness: improve test coverage and QA
> ------------------------------------------------------------
>
> Key: SPARK-59298
> URL: https://issues.apache.org/jira/browse/SPARK-59298
> Project: Spark
> Issue Type: Umbrella
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Luka Zdravic
> Priority: Minor
>
> ASOF JOIN was recently added to Spark SQL across several PRs — parser
> (SPARK-58122), analysis (SPARK-58123), physical execution (SPARK-58124),
> golden-file tests (SPARK-58173), and documentation (SPARK-58176)
> Reviewing the implementation against the ASOF JOIN SQL reference surfaced
> gaps in the unit-test coverage across the parser, analyzer, planner, and
> physical-operator layers.
> This umbrella tracks focused, layer-by-layer, test-only follow-ups that close
> those gaps.
> Linked issues:
> - Parser unit tests
> - ResolveAsOfJoin (analyzer) unit tests
> - AsOfJoinSelection (planner) unit tests
> - SortMergeAsOfJoinExec (execution) edge-case unit tests (added as the
> review proceeds)
