> What's the longer term goal with this, especially in the context of all the attempts to add CSE to conditional expressions? I think the final state should be implementing CSE at the logical plan level, so that it works for both codegen backend and native (vectorized) backend. But we still have gaps now. The `With` expression only works for operators that can add extra projects. It doesn't work for join conditions, while codegen is more flexible. Also codegen CSE is more adaptive and can be used for conditional expressions, but `With` is static. Before filling the gaps, `With` can't replace the current codegen CSE. -- This is an automated message from the Apache Git Service.
