> After playing around with this, I have become convinced what is really needed is a "TreeMutator" type API on TreeNode that lets us rewrite `LogicalNode`s in place -- if we had that API I think we can make the DataFusion Optimizer screaming fast It seems treemutaor is `&mut T` at the first place, and in your previous design #9708 we have `&mut T` for `rewrite_inputs` and `rewrite_exprs`, I don't understand why the former one is better, I guess they have the similar performance. -- This is an automated message from the Apache Git Service.
