ClassDescriptionThe various "states" exchanged through Gossip.This abstraction represents both the HeartBeatState and the ApplicationState in an EndpointState instance.This FailureDetector is an implementation of the paper titled "The Phi Accrual Failure Detector" by Hayashibara.Contains information about a specified list of Endpoints and the largest version of the state they have generated as known by the local endpoint.This ack gets sent out as a result of the receipt of a GossipDigestSynMessage by an endpoint.This ack gets sent out as a result of the receipt of a GossipDigestAckMessage.This is the first message that gets sent out as a start of the Gossip protocol in a round.This module is responsible for Gossiping information for the local endpoint.DiagnosticEvent implementation for
Gossiperactivities.HeartBeat State associated with any given endpoint.This is called by an instance of the IEndpointStateChangePublisher to notify interested parties about changes in the the state associated with any endpoint.Implemented by the Gossiper to convict an endpoint based on the PHI calculated by the Failure Detector on the inter-arrival times of the heart beats.An interface that provides an application with the ability to query liveness information of a node in the cluster.This abstraction represents the state associated with a particular node which an application wants to make available to the rest of the nodes in the cluster.A unique version number generator for any state that is generated by the local node.
