Re: [infinispan-dev] Async Notification API

While the new async API has been getting rave reviews, someone did bring up async notifications. E.g., Future f = cache.putAsync(k, v); f.get(); But what if I don't want to wait on f.get(), I'd rather be told when the future is done so I can do an f.get()? Sounds pretty useful to me. But just wanted to sound you guys on the API choices for notifications. My immediate thought was to use the existing notification API. You register a cache listener, annotate a method with @RpcCallMade, receive an RpcCallMadeEvent. But this is probably pretty useless, since you couldn't associate the notification with the specific put you've just done. Even if you have the key in the event (which is unlikely - since we need to use the same event for all cache operations, some which take > 1 key such as putAll()), multiple threads could be working on the same key. Another approach is to design a sub-interface to Future. NotifyingFuture. public interface NotifyingFuture extends Future { void addListener(NotifyingFutureListener l); } public interface NotifyingFutureListener { void futureDone(Future f); } WDYT? -- Manik Surtani manik(a)jboss.org Lead, Infinispan Lead, JBoss Cache http://www.infinispan.org http://www.jbosscache.org _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
