AdaptiveLoadBalancingGroup

final case class AdaptiveLoadBalancingGroup(metricsSelector: MetricsSelector = MixMetricsSelector, paths: Iterable[String] = Nil, routerDispatcher: String = Dispatchers.DefaultDispatcherId) extends Group with Product with Serializable

A router group that performs 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.

The configuration parameter trumps the constructor arguments. This means that if you provide paths during instantiation they will be ignored if the router is defined in the configuration file for the actor being used.

metricsSelector

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

paths

string representation of the actor paths of the routees, messages are sent with akka.actor.ActorSelection to these paths

routerDispatcher

dispatcher to use for the router head actor, which handles router management messages
