trait ShardedDaemonProcess extends Extension

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.

Abstract Value Members

  1. abstract def init[T](name: String, numberOfInstances: Int, behaviorFactory: (Int) ⇒ Behavior[T], settings: ShardedDaemonProcessSettings, stopMessage: Option[T])(implicit classTag: ClassTag[T]): 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 0 until numberOfInstance create the behavior for that actor.

    stopMessage

    if defined sent to the actors when they need to stop because of a rebalance across the nodes of the cluster or cluster shutdown.

  2. abstract def init[T](name: String, numberOfInstances: Int, behaviorFactory: (Int) ⇒ Behavior[T], stopMessage: T)(implicit classTag: ClassTag[T]): Unit

    Start a specific number of actors that is then kept alive in the cluster.
