> Would this transformation be something you can detect and apply within an existing (or new) optimizer rule? Or do you actually need a dedicated rule that **prevents** the two-step aggregation from being generated in the first place? The original, and to me most most intuitive way of doing it is adding this transformation to an existing rule. But this is something to think about as it could save overhead to prevent it before it is produced at all. I will look at some more apporaches with this in mind and see what I come up with. -- This is an automated message from the Apache Git Service.
