One possible solution in this rule is when you collect possible_join_keys , when you see a Projection, if the collected join keys from the children are not in the output of the projection, should remove them from the possible_join_keys, because they are not visible to the top plan. And when you push down the top level filter conditions into Joins, need to respect the Alias and Projection and should tranform the name to name before the Projection. -- This is an automated message from the Apache Git Service.
