Package tigase.pubsub.cluster

Class ClusteredNodeStrategy

java.lang.Object
tigase.pubsub.cluster.AbstractStrategy
tigase.pubsub.cluster.ClusteredNodeStrategy
All Implemented Interfaces:
tigase.kernel.beans.Initializable, tigase.kernel.beans.UnregisterAware, StrategyIfc
@Bean(name="strategy", parent=PubSubComponentClustered.class, active=true) public class ClusteredNodeStrategy extends AbstractStrategy implements StrategyIfc
ClusteredNodeStrategy - all pubsub nodes are shared between all cluster nodes, which implies forwarding of packet information across the cluster with the exception of create/remove operation on nodes (to avoid race conditions).
