Interface ReplicationTracker

All Known Implementing Classes:

ReplicationTrackerZKImpl

@InterfaceAudience.Private
public interface ReplicationTracker

This is the interface for a Replication Tracker. A replication tracker provides the facility to subscribe and track events that reflect a change in replication state. These events are used by the ReplicationSourceManager to coordinate replication tasks such as addition/deletion of queues and queue failover. These events are defined in the ReplicationListener interface. If a class would like to listen to replication events it must implement the ReplicationListener interface and register itself with a Replication Tracker.
