I investigated this and found that SPJ works correctly after partition evolution when all data files use the new spec — `SparkPartitioningAwareScan.specs()` only considers specs with actual data, so the grouping key computation should work after a successful `rewrite_data_files` + `expire_snapshots`. Could you check if any files still reference the old spec after your cleanup? ```sql SELECT spec_id, count(*) FROM <catalog>.<db>.<table>.files GROUP BY spec_id; DESCRIBE EXTENDED <catalog>.<db>.<table>; ``` If old-spec files remain, that would explain the empty grouping key. -- This is an automated message from the Apache Git Service.
