org.elasticsearch.action.support.TransportAction<Request,Response>

org.elasticsearch.action.support.replication.TransportReplicationAction<Request,ReplicaRequest,Response>

org.elasticsearch.action.support.replication.TransportWriteAction<RetentionLeaseSyncAction.Request,RetentionLeaseSyncAction.Request,RetentionLeaseSyncAction.Response>

org.elasticsearch.index.seqno.RetentionLeaseSyncAction

public class RetentionLeaseSyncAction
extends TransportWriteAction<RetentionLeaseSyncAction.Request,RetentionLeaseSyncAction.Request,RetentionLeaseSyncAction.Response>

Write action responsible for syncing retention leases to replicas. This action is deliberately a write action so that if a replica misses a retention lease sync then that shard will be marked as stale.
