> High level, introducing `replace` action changes seem fine to me, interested in learning how old_file_group -> new_file_group mapping is stored and accessed. Yet to review the other PRs if they have this info.. This is not 1:1 mapping. So this is not being stored in replace metadata file. We can get new file groups created from corresponding commit metadata file. As far as I can see, we only need this information for auditing, debugging. So I'm planning to build this with CLI task. Let me know if you see this useful in other scenarios. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
