Class PeerRecoveryTargetService
java.lang.Object
org.elasticsearch.indices.recovery.PeerRecoveryTargetService
- All Implemented Interfaces:
IndexEventListener
public class PeerRecoveryTargetService extends java.lang.Object 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).

getStartRecoveryRequest
public static StartRecoveryRequest getStartRecoveryRequest(org.apache.logging.log4j.Logger logger, DiscoveryNode localNode, RecoveryTarget recoveryTarget, long startingSeqNo)Prepare the start recovery request.- Parameters:
logger
- the loggerlocalNode
- the local node of the recovery targetrecoveryTarget
- the target of the recoverystartingSeqNo
- a sequence number that an operation-based peer recovery can start with. This is the first operation after the local checkpoint of the safe commit if exists.- Returns:
- a start recovery request
