Clearly separating the logic / transformations needed for the plan to produce the correct answers and the transformations that aim to make it go faster (e.g. optimizations) makes a lot of sense to me. One approach that seems reasonable to me would be to take the pass in https://github.com/apache/arrow-datafusion/blob/master/datafusion/src/physical_optimizer/merge_exec.rs and call it directly from the `DefaultPhysicalPlanner` always. Depending on where else it is used, we may even consider not exposing it as a `PhysicalOptimizerRule` -- This is an automated message from the Apache Git Service.
