> Current DML implementation is not transactional. It groups keys in batches by their affinity, and then flushes that batches synchronously. This could lead to deadlocks easily.
> This could be improved if we sort key within a batch. However, this would require new comparison function for {{BinaryObjectImpl}}, as it is not comparable.
