12.4. NotifyingFutures

Methods in Red Hat JBoss Data Grid do not return Java Development Kit (JDK) Futures, but a sub-interface known as a NotifyingFuture. Unlike a JDK Future, a listener can be attached to a NotifyingFuture to notify the user about a completed future.

Note

NotifyingFutures are only available in JBoss Data Grid Library mode.

         // Future did not complete successfully         
         System.out.println("Help!");
      }
   }
};
      
cache.putAsync("key", "value").attachListener(futureListener);
