------------------------------------
Summary: 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
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)
