Class AdaptiveLoadBalancingRoutingLogic

  • All Implemented Interfaces:
    NoSerializationVerificationNeeded, RoutingLogic,, scala.Equals, scala.Product

    public final class AdaptiveLoadBalancingRoutingLogic
    extends java.lang.Object
    implements RoutingLogic, NoSerializationVerificationNeeded, scala.Product,
    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.

    param: system the actor system hosting this router

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

        Description copied from interface: RoutingLogic
        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.
