Class BlobRecoverySourceHandler

java.lang.Object

org.elasticsearch.indices.recovery.RecoverySourceHandler

org.elasticsearch.indices.recovery.BlobRecoverySourceHandler

All Implemented Interfaces:

org.elasticsearch.index.engine.Engine.RecoveryHandler

public class BlobRecoverySourceHandler
extends org.elasticsearch.indices.recovery.RecoverySourceHandler

RecoverySourceHandler handles the three phases of shard recovery, which is everything relating to copying the segment files as well as sending translog operations across the wire once the segments have been copied. Copied from RecoverySourceHandler, extends only phase1.

Method Detail

phase1

public void phase1(org.elasticsearch.index.deletionpolicy.SnapshotIndexCommit snapshot)
            throws org.elasticsearch.ElasticsearchException

Perform phase1 of the recovery operations. Once this SnapshotIndexCommit snapshot has been performed no commit operations (files being fsync'd) are effectively allowed on this index until all recovery phases are done Phase1 examines the segment files on the target node and copies over the segments that are missing. Only segments that have the same size and checksum can be reused InternalEngine#recover is responsible for snapshotting the index and releasing the snapshot once all 3 phases of recovery are complete

Specified by:

phase1 in interface org.elasticsearch.index.engine.Engine.RecoveryHandler

Overrides:

phase1 in class org.elasticsearch.indices.recovery.RecoverySourceHandler

Throws:

org.elasticsearch.ElasticsearchException
