It is hard to explain, but in short my master actor receives a message which is then forwarded to the respective worker, and from that message I extract business information to make my worker's (FSM) persistenceId unique.
After I second thought, maybe I misunderstood the router concept - I just realized that this code load balances the work between the actors, but you are right, I need to find a way how to distribute it equally among the nodes which I suppose is done by the cluster sharding.
