New to clustering and singleton looks sufficient for me. Two questions:
a) If I create a singleton(s) with two roles (“A” and “B”), but set the actorProxy to not use roles, does it pick up one or the other? What happens if the one that we are using is down (say “A”) but the other singleton is up (say “B”)?
b) When a singleton actor becomes “it”, is there a preStart() that can be called? I noticed ClusterListener in the generic Cluster framework. Is there a singleton specific way?
