"Oracle NoSQL Database supports the ability to bundle a collection of operations together using the execute method, providing transactional semantics across multiple updates on records with the same Major Key Path." In other words, ot supports transactions as long as the key-values are on the same replica group (as they call it). That's easy for them, since they just run a BerkeleyDB HA instance per replica group, and that supports transactions.
