@liningpan I don't think that's related to this issue, but it is a very valid point. Could you maybe open an issue to track that? Off the top of my head it feels like something the CSE (Common Sub-expression Elimination) optimizer might be able to handle. A good first step would be an MRE / benchmark showing the perf issue (you could write a UDF that has a sleep in it or something). -- This is an automated message from the Apache Git Service.
