Package org.elasticsearch.cluster.coordination

Class Join

java.lang.Object

org.elasticsearch.cluster.coordination.Join

All Implemented Interfaces:

Writeable

public class Join
extends Object
implements Writeable

Triggered by a StartJoinRequest, instances of this class represent join votes, and have a source and target node. The source node is the node that provides the vote, and the target node is the node for which this vote is cast. A node will only cast a single vote per term, and this for a unique target node. The vote also carries information about the current state of the node that provided the vote, so that the receiver of the vote can determine if it has a more up-to-date state than the source node.
