> You will need to re-implement a propagation framework, as not only the direct parent of the join can access the hidden columns. e.g. Sort -> Project -> Join, we can sort by the join hidden column OK, let me think more on this recently. I feel that mixing the V2 metadata columns and the hidden join columns are hard to maintain. A bit of duplicate code for the propagation can make future development easier. -- This is an automated message from the Apache Git Service.
