> 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 I think a `LogicalPlan` tree is made of `Arc` links between the nodes currently. So I wonder if obtaining mutable references to a `LogicalPlan` node's children is possible at all without cloning the children first? -- This is an automated message from the Apache Git Service.
