Thank you for the suggestion @2010YOUY01 ! I was actually stuck on how to handle the optimizer rules to satisfy that first benefit without a massive refactoring. I think that the ideal long-term solution is to equip UDFs with "properties" (like associativity or commutativity). This would allow the optimizer to handle them generically, which would also benefit user-defined functions. But as you noted, that would require a significant overhaul. I agree your proposed middle ground is a great practical trade-off. I will try to create a new POC based on this wrapping approach. Hope this can serve as a starting point, and that we can eventually find a better way to unify the two frameworks step-by-step. -- This is an automated message from the Apache Git Service.
