## Which issue does this PR close? - Closes ##22964 ## Rationale for this change We presently allow dynamic filter pushdown to be applied to null-equal hash joins. This might result in pushing a predicate down into the probe-side plan, where the predicate will not be evaluated with the null-equal semantics that are required. Longer-term, we might consider supporting this case with the correct semantics (e.g., generate a predicate with `OR IS NULL ...`), but for now disabling pushdown for null-equal joins seems much more practical. ## What changes are included in this PR? * Disable hash join dynamic filter pushdown for null-equal joins * Add SLT test with end-to-end repro * Add unit test ## Are these changes tested? Yes. ## Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service.
