Method Details

shardInitialized

public void shardInitialized(ShardRouting unassignedShard,
 ShardRouting initializedShard)

Description copied from interface: RoutingChangesObserver

Called when unassigned shard is initialized. Does not include initializing relocation target shards.

Specified by:

shardInitialized in interface RoutingChangesObserver

shardStarted

public void shardStarted(ShardRouting initializingShard,
 ShardRouting startedShard)

Description copied from interface: RoutingChangesObserver

Called when an initializing shard is started.

Specified by:

shardStarted in interface RoutingChangesObserver

relocationStarted

public void relocationStarted(ShardRouting startedShard,
 ShardRouting targetRelocatingShard)

Description copied from interface: RoutingChangesObserver

Called when relocation of a started shard is initiated.

Specified by:

relocationStarted in interface RoutingChangesObserver

unassignedInfoUpdated

public void unassignedInfoUpdated(ShardRouting unassignedShard,
 UnassignedInfo newUnassignedInfo)

Description copied from interface: RoutingChangesObserver

Called when an unassigned shard's unassigned information was updated

Specified by:

unassignedInfoUpdated in interface RoutingChangesObserver

shardFailed

public void shardFailed(ShardRouting activeShard,
 UnassignedInfo unassignedInfo)

Description copied from interface: RoutingChangesObserver

Called when a shard is failed or cancelled.

Specified by:

shardFailed in interface RoutingChangesObserver

relocationCompleted

public void relocationCompleted(ShardRouting removedRelocationSource)

Description copied from interface: RoutingChangesObserver

Called on relocation source when relocation completes after relocation target is started.

Specified by:

relocationCompleted in interface RoutingChangesObserver

relocationSourceRemoved

public void relocationSourceRemoved(ShardRouting removedReplicaRelocationSource)

Description copied from interface: RoutingChangesObserver

Called on replica relocation target when replica relocation source fails. Promotes the replica relocation target to ordinary initializing shard.

Specified by:

relocationSourceRemoved in interface RoutingChangesObserver

replicaPromoted

public void replicaPromoted(ShardRouting replicaShard)

Description copied from interface: RoutingChangesObserver

Called when started replica is promoted to primary.

Specified by:

replicaPromoted in interface RoutingChangesObserver

initializedReplicaReinitialized

public void initializedReplicaReinitialized(ShardRouting oldReplica,
 ShardRouting reinitializedReplica)

Description copied from interface: RoutingChangesObserver

Called when an initializing replica is reinitialized. This happens when a primary relocation completes, which reinitializes all currently initializing replicas as their recovery source node changes

Specified by:

initializedReplicaReinitialized in interface RoutingChangesObserver
