Class RecoverySourceHandler

java.lang.Object

org.elasticsearch.indices.recovery.RecoverySourceHandler

public class RecoverySourceHandler
extends Object

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. Note: There is always one source handler per recovery that handles all the file and translog transfer. This handler is completely isolated from other recoveries while the RateLimiter passed via RecoverySettings is shared across recoveries originating from this nodes to throttle the number bytes send during file transfer. The transaction log phase bypasses the rate limiter entirely.
