This issue was reviewed as part of the JIRA-migrated backlog triage (HUDI-9549). **Findings: still open.** A feature gap with a clear acceptance test: `select * from mytable where secCol is null` should trigger a secondary index lookup and currently does not. Relevant context from the same batch: #17068 (HUDI-9550) lists "null value handling" as one of the secondary-index changes for table version 9 that needs documenting. That suggests null semantics for SI were recently defined - so this may now be implementable in a way it was not when filed. Worth checking that work first, since the index's on-disk representation of nulls determines whether an `is null` predicate can be answered from the index at all.
