@Dandandan @alamb ready for another round of review. Given this PR has grown into 900 lines, I think it would be better to work on a new `ExprRewriter` refactor only PR to ease the review process. We will be able to get a better idea of how the new framework works by applying it to multiple optimization rules in the same patch set. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
