I think that code is just used in `catalog.system.rewrite_table_path procedure`, not in the MERGE of the Job. So MERGE-time DV rewriting = load the previous bitmap, union it with the new deletes, write a fresh Puffin file, and drop the old DV in the same RowDelta commit. In Spark this is driven by `SparkPositionDeltaWrite` wrapping `BaseDVFileWriter`. That's the streaming/MERGE path. -- This is an automated message from the Apache Git Service.
