> Quoting:
> So i was able to reproduce behavior that you're seeing and it turns out to be that {{_hoodie_file_name}} is simply not updated during Commit 3, meaning that during C3, all records are copied from latest base-file of the file-group into new latest base-file (in your most recent experiment it's {{{}c872d135-bf8f-4c5e-9eee-6347635c32d3-0_0-21-22_20220406182741563.parquet{}}}) but it doesn't update the {{_hoodie_file_name}} field which is kept pointing at the old file.
