Concurrent RowDelta commits that add DVs for the same data file always fail validation with `Found concurrently added DV`, even though position deletes are commutative. Under concurrent DELETE workloads on V3 tables this makes commits fail without any real conflict. When the RowDelta does not add or remove data files and `validateNoConflictingDeleteFiles` is not enabled, this change merges the concurrently added DV into the operation's DV for the same data file instead of failing. The V3 spec requires a DV to include all deleted positions from the DV it replaces, so the newest concurrent DV for a data file contains the content of all older ones. That DV is removed from the table and its content is merged into the new DV. Pending removals of delete files for that data file are dropped because the concurrent commits already removed them. Merged puffin files written by invalidated commit attempts are deleted on retry and on commit failure. -- This is an automated message from the Apache Git Service.
