public interface QuorumFunction
HeartbeatAwarewill be also notified of heartbeats. Additionally, a
MembershipListenerwill be notified of membership events. All listener invocations are executed before the
apply(Collection)method is invoked. IMPORTANT: The term "quorum" simply refers to the count of members in the cluster required for an operation to succeed. It does NOT refer to an implementation of Paxos or Raft protocols as used in many NoSQL and distributed systems. The mechanism it provides in Hazelcast protects the user in case the number of nodes in a cluster drops below the specified one.
|Modifier and Type||Method and Description|
