Package org.elasticsearch.indices.recovery

Class PeerRecoveryTargetService

java.lang.Object

org.elasticsearch.common.component.AbstractComponent

org.elasticsearch.indices.recovery.PeerRecoveryTargetService

All Implemented Interfaces:

IndexEventListener

public class PeerRecoveryTargetService
extends AbstractComponent
implements IndexEventListener

The recovery target handles recoveries of peer shards of the shard+node to recover to.

Note, it can be safely assumed that there will only be a single recovery per shard (index+id) and not several of them (since we don't allocate several shard replicas to the same node).
