8.7. About Replication Guarantees

In a clustered cache, the user can receive synchronous replication guarantees as well as the parallelism associated with asynchronous replication. Red Hat JBoss Data Grid provides an asynchronous API for this purpose.
The asynchronous methods used in the API return Futures, which can be queried. The queries block the thread until a confirmation is received about the success of any network calls used.
