Re: [akka-user] Create an FSM actor outside a cluster and initialize it with references to another actors in the cluster
Hi Eugene, You could have the creation of actor A (and subsequently the B actors) done by a master actor that represents a service inside the cluster, and the response you get from that master contains a named topic or something similar where the FSM can communicate with the A actor. Have you looked at the distributed workers Activator template? It uses the cluster singleton as well as the cluster client to implement fan out of work to multiple nodes.

The biggest problem is that the original system was developed without any clustering in mind - so on every request from the client, a new FSM actor is created, some pre-defined references to worker actors are passed to the FSM actor and then it orchestrates the workers to get the job done.

[akka-user] Create an FSM actor outside a cluster and initialize it with references to another actors in the cluster
Hello! I have an FSM actor. which takes a number of references to worker actors in it's constructor. That works very well if there's a single actor system. Now I want to create another worker actor *in the cluster* and get a reference to this actor in the FSM actor *outside of the cluster*, so it will be able to send messages to the clustered actor and receive responses. I don't need to create those worker actors in the cluster in advance - only when needed (and the number of created actors may vary). This new worker actor will create and coordinate subset of another actors in the cluster. not visible to the FSM actor. I've studied the *Cluster Client*, but it seems that the ClusterClient may only work with some pre-existing actors and can't create new ones on demand. Please advice.
