- abstract def init[T](messageClass: Class[T], name: String, numberOfInstances: Int, behaviorFactory: [Behavior[T]], settings: ShardedDaemonProcessSettings, stopMessage: Optional[T], shardAllocationStrategy: [ShardAllocationStrategy]): Unit
Start a specific number of actors, each with a unique numeric id in the set, that is then kept alive in the cluster.
Start a specific number of actors, each with a unique numeric id in the set, that is then kept alive in the cluster.
- behaviorFactory
Given a unique id of

This extension runs a pre set number of actors in a cluster.
The typical use case is when you have a task that can be divided in a number of workers, each doing a sharded part of the work, for example consuming the read side events from Akka Persistence through tagged events where each tag decides which consumer that should consume the event.
Each named set needs to be started on all the nodes of the cluster on start up.
The processes are spread out across the cluster, when the cluster topology changes the processes may be stopped and started anew on a new node to rebalance them.
Not for user extension.
