My system is actually using local actors in much the same way you describe -- there's a cluster-singleton Coordinator, but a single local Manager per node, and the Manager does the SBR work. Indeed, I *think* it's strictly necessary to have a single local actor per-node for any good solution. (Although, again, I'm not an expert.) In the long run, I have some airy theories about using AWS to make the architecture more robust (since AWS theoretically has a "god's-eye" view of which nodes are up), but I haven't spent enough time on that yet to figure out whether it really works as a solution. -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
