Class RoutingService

java.lang.Object

org.elasticsearch.common.component.AbstractComponent

org.elasticsearch.common.component.AbstractLifecycleComponent<RoutingService>

org.elasticsearch.cluster.routing.RoutingService

All Implemented Interfaces:

AutoCloseable, ClusterStateListener, LifecycleComponent<RoutingService>, Releasable

public class RoutingService
extends AbstractLifecycleComponent<RoutingService>
implements ClusterStateListener

A RoutingService listens to clusters state. When this service receives a ClusterChangedEvent the cluster state will be verified and the routing tables might be updated.

Note: The RoutingService is responsible for cluster wide operations that include modifications to the cluster state. Such an operation can only be performed on the clusters master node. Unless the local node this service is running on is the clusters master node this service will not perform any actions.
