java.lang.Object akka.cluster.routing.AdaptiveLoadBalancingGroup
public final class AdaptiveLoadBalancingGroup
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.
param: metricsSelector decides what probability to use for selecting a routee, based on remaining capacity as indicated by the node metrics
param: paths string representation of the actor paths of the routees, messages are
sent with ActorSelection
to these paths
param: routerDispatcher dispatcher to use for the router head actor, which handles router management messages
