E.g., multiple calls to cache.put() will result in multiple replication events but if you wrap these in a transaction, then replication occurs when the transaction commits, as a single message, which could be more efficient. | | Isolation level applies to in-memory locking as well so it is relevant even if you are not using a TM. | Thanks for that Manik.
