@J-HowHuang Yes, once the transform is added, updated, or removed, reload applies that to existing auto-generated derived columns. Legacy segments that have no stored transform are a metadata-only backfill on first reload, then the next real change rebuilds values. There is no opt-out in this PR for keeping the old transform on old segments. If we want that door, I would rather do it as a follow-up than add a public flag here. -- This is an automated message from the Apache Git Service.
