org.elasticsearch.snapshotsでのClusterStateListenerの使用

ClusterStateListenerを実装しているorg.elasticsearch.snapshotsのクラス

修飾子とタイプ	クラスと説明
class	RestoreService Service responsible for restoring snapshots Restore operation is performed in several stages.
class	SnapshotShardsService This service runs on data and master nodes and controls currently snapshotted shards on these nodes.
class	SnapshotsService Service responsible for creating snapshots A typical snapshot creating process looks like this: On the master node the SnapshotsService.createSnapshot(SnapshotRequest, CreateSnapshotListener) is called and makes sure that no snapshots is currently running and registers the new snapshot in cluster state When cluster state is updated the SnapshotsService.beginSnapshot(ClusterState, SnapshotsInProgress.Entry, boolean, CreateSnapshotListener) method kicks in and initializes the snapshot in the repository and then populates list of shards that needs to be snapshotted in cluster state Each data node is watching for these shards and when new shards scheduled for snapshotting appear in the cluster state, data nodes start processing them through SnapshotShardsService.processIndexShardSnapshots(ClusterChangedEvent) method Once shard snapshot is created data node updates state of the shard in the cluster state using the SnapshotShardsService.updateIndexShardSnapshotStatus(org.elasticsearch.cluster.metadata.SnapshotId, org.elasticsearch.index.shard.ShardId, org.elasticsearch.cluster.SnapshotsInProgress.ShardSnapshotStatus) method When last shard is completed master node in SnapshotShardsService.innerUpdateSnapshotState(org.elasticsearch.snapshots.SnapshotShardsService.UpdateIndexShardSnapshotStatusRequest) method marks the snapshot as completed After cluster state is updated, the SnapshotsService.endSnapshot(SnapshotsInProgress.Entry) finalizes snapshot in the repository, notifies all SnapshotsService.snapshotCompletionListeners that snapshot is completed, and finally calls SnapshotsService.removeSnapshotFromClusterState(SnapshotId, SnapshotInfo, Throwable) to remove snapshot from cluster state
