This used to be called "discrete transactions", which were useless except for cheating on benchmarks, primarily TPC-C. There was a huge row and Oracle has left TPC for 6 months or so because of that. This feature disappeared after that and all was well in the harmonious family of relational databases. This "new feature" really raises my eyebrows.
