ASF GitHub Bot updated SPARK-59326:
-----------------------------------
Labels: pull-request-available (was: )
> Add missing ASOF JOIN match-condition type unit tests
> -----------------------------------------------------
>
> Key: SPARK-59326
> URL: https://issues.apache.org/jira/browse/SPARK-59326
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Luka Zdravic
> Priority: Minor
> Labels: pull-request-available
>
> AsOfJoinMatchConditionTypesSuite unit-tests the MatchConditionTypes
> operand-type predicates used by ASOF JOIN analysis, but omits the
> non-orderable-type and struct field-type-mismatch cases. Those scenarios are
> currently only exercised end-to-end (golden join-asof-errors.sql) or not at
> all, with no direct unit assertion on the predicate.
> Add:
> - MAP operands are invalid (not orderable);
> - ARRAY operands whose element type is non-orderable are invalid;
> - STRUCT operands with a non-orderable field are invalid;
> - positional STRUCT operands with the same field count but an incompatible
> field-type pair are rejected (currently only field-count mismatch is covered).
> Test-only; no production code changes. Complements the functional coverage in
> AsOfJoinSQLSuite.
> Umbrella: SPARK-59298
