Hi Ugo, Have you looked at the Cluster Singleton module? http://doc.akka.io/docs/akka/2.3.10/contrib/cluster-singleton.html
It solves this issue and also migration of the singleton on failures. I think you are better of using that module than trying to roll your own. -Endre On Fri, May 8, 2015 at 4:14 PM, Ugo Matrangolo <[email protected]> wrote: > Hi, > > started to play with Akka remoting and I hit a problem with singleton > actors. > > I have a 3 nodes Akka cluster with a singleton actor running somewhere > under the /user/root/singleton path. > > I would like to send a message to this actor from any node in the cluster > triggered by someone hitting a Play Controller endpoint. > > AFAIK, what I need to do is to get the ActorRef using: > > actorSystem.actorSelection("akka.tcp://mySystem@node1 > :2551/user/root/singleton") > > What I don't like is that I need to know *where* the singleton actor is > running (e.g. node1:2551). > > Is there a way to broadcast a query like "Are you there?" to all nodes > having the singleton actor respond with an Identify ?? > > What I'm trying to achieve is something like: > > > > actorSystem.actorSelection("akka.tcp://mySystem/user/root/singleton").mapTo[ActorRef] > !
