RewriteFiles might be used to compact a table, e.g. it can replace lots of small files with a few big files. Concurrent RowDelta (DELETE/ UPDATE) operations must fail, because they can put the table in an inconsistent state. A successful DELETE (with merge-on-read) can become a no-op as the position delete files refer to the replaced small files. A successful UPDATE (with merge-on-read) can duplicate rows as the delete files refer to the replaced small files, and it also adds its own data files. -- This is an automated message from the Apache Git Service.
