commit da63b55148f0f4a49050338539b1bc1ab250a76e Author: Gabriel <[email protected]> AuthorDate: Sun Oct 11 12:54:50 2026 +0800 [fix](regression) Stabilize Paimon Rust IN filter checks on branch-4.1 (#68899) ### What problem does this PR solve? The Paimon Rust reader regression expects its small integer IN runtime filter to reach the reader, but inherits `runtime_filter_max_in_num`. Fuzzy sessions can set this limit to zero, disabling the filter before it reaches Rust even with `runtime_filter_wait_infinitely=true`. The query remains correct while the positive pushdown assertion fails. Set the limit to 1024 before the pushdown checks. The existing large-set checks still use 70000, and the existing `finally` block restores the original limit. All result and profile assertions remain intact. Target: `branch-4.1`. ### Validation Ran the complete `test_paimon_rust_reader_eq_for_null` suite against a local three-BE branch-4.1 CI build with Spark 4.0, Paimon 1.4.2 and MinIO: - Original suite, normal limit: passed. - Original suite, initial `runtime_filter_max_in_num=0`: failed at the integer IN pushdown assertion; the probe reported input/applied counters of 0/0. - Patched suite, the same initial limit of 0: passed (1 suite, 0 failures, 0 skipped); the probe reported 1/1 and the suite restored the original limit to 0. - `git diff --check`: passed. ### Release note None.
