Igniters, Current implementation of DML is not transactional. We have not guarantees on what is updated and what is not. When certain update fails due to concurrent entry change, we perform a retry.
The thing is that re-try doesn't guarantee anything still and it might introduce subtle performance degradation in case of complex queries. As it has no value for users, I propose to drop it altogether. Semantically nothing will change from user perspective as we have no guarantees. Thoughts? Vladimir.
