I've create [ISPN-3897] Listener with @ViewChanged annotation for RemoteCacheManager. - JBoss Issue Tracker task for this.
Usage of this is that RemoteCacheManager clients of HotRod servers would know when and how topology of network has changed. Usage of such a notification for clients can be in scenarios where e.g. you will be notified when Hotrod server went down and because of that some action from Client side is needed to be invoked.
