I recommend to start after the refactor - https://github.com/apache/datafusion/issues/24791 When we added spilling for NLJ, I feel the implementation is unnecessarily complex, and some existence-join-specific optimizations are really hard to route into the existing logic. Multiplexed implementation is likely the culprit, and I think it will happen in HJ similarly. I'll give it a try shortly to see if we can make the HJ implementation simpler first. -- This is an automated message from the Apache Git Service.
