This change does not create and materialize all query stages of the join in a batch. It creates and materialize one stage first and then re-optimize the join. So once it makes the join as broadcast join, it won't create the unnecessary exchange. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
