I'm not aware of any, although I'm not sure Datomic qualifies as a traditional DBMS. It's more like a querying API + a master process (transactor) backed by a traditional store/DB (Postgres, Dynamo, etc), so you can achieve the same by putting some existing solutions together, but it's implementing a bit more than a DBMS alone.
