Class ClusterStateManager

java.lang.Object

com.hazelcast.internal.cluster.impl.ClusterStateManager

public class ClusterStateManager
extends Object

ClusterStateManager stores cluster state and manages cluster state transactions.

When a node joins to the cluster, its initial state is set.

When a cluster state change is requested, a cluster-wide transaction is started and state is changed all over the cluster atomically.
