Sometimes this is slower than serialization. In fact, when you’re doing KV-CRUD work on in-memory data, it’s often slower than serialization. Keeping RW-sets is non-trivial overhead compared to the hardest typical part of KV-CRUD, tree or hash lookups. Many many systems have more parallelism, but less throughput. Now, if you want to prevent one transaction with a bad-actor blocking the system, then RW-sets, timeouts and OCC/MVCC might be a good idea, it just won’t be faster.
