I believe the difference is: the earlier implementation looked at all of the plans in the `from` clause when selecting a join, while the optimization rule processes the tree in order and only replaces a cross join with an inner join when it's possible. Some transformations from cross join to inner join however need reordering of the joins within the tree in order for this to be possible. -- This is an automated message from the Apache Git Service.
