AdaptiveLoadBalancingRoutingLogic

final case class AdaptiveLoadBalancingRoutingLogic(system: ActorSystem, metricsSelector: MetricsSelector = MixMetricsSelector) extends RoutingLogic with NoSerializationVerificationNeeded with Product with Serializable

Load balancing of messages to cluster nodes based on cluster metric data.

It uses random selection of routees based on probabilities derived from the remaining capacity of corresponding node.

system

the actor system hosting this router

metricsSelector

decides what probability to use for selecting a routee, based on remaining capacity as indicated by the node metrics

  3. def select(message: Any, routees: IndexedSeq[Routee]): Routee

    Pick the destination for a given message.

    Pick the destination for a given message. Normally it picks one of the passed routees, but in the end it is up to the implementation to return whatever Routee to use for sending a specific message.

    When implemented from Java it can be good to know that routees.apply(index) can be used to get an element from the IndexedSeq.
