### Is your feature request related to a problem or challenge? Under `NullEqualsNothing`, it would be better to omit build-side rows whose join keys contain a NULL. This reduces the size of the hash table and avoids some wasted work. Because every NULL build row will belong to a single hash chain, we'll do quite a bit of wasted work at probe-time for every NULL probe row. ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
