Please assign more memory to InMemoryHashJoin."); > As we both know, the old contract works because it ignores the hash table f The current contract seems changed because in-memory hash join can potentially fail. Yes, it counts the hash table footprint, but the optimized hybrid hash join should guarantee that even in the worst case, in-memory hash join should always work within the memory budget, i.e., the exception should never be hit.
