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

select

public Routee select(java.lang.Object message,
                     scala.collection.immutable.IndexedSeq<Routee> routees)
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.
