Just to be sure: that means having something like a singleton actor which persists the events in the cluster? And several others as views to deliver read requests? What if I want to have multiple persistent actors of the same type based on resilient reasons?

Each node has a persistent actor which should write to cassandra the events which have been created and update their inner state afterwards. Now I'm asking myself what is the best approach to inform the other nodes about that change because they also need to know the state change? * use the distributed pub sub (and therefore create a cluster)? * use remote actors to directly inform the other nodes about the change? * other solution? It is probably easiest to replicate the events with PersistentView. The other approaches can also work, but be aware of: - messages can be lost - when a node is started it might need to get the initial state from the other nodes Regards, Patrik Thanks and best regards Martin -- >>>>>>>>>> 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.
