Clients just specify the type of events that they are interested in, and the content that the event should at least contain. Clients do not need to maintain an active presence during the time these interesting events are taking place. Once it registers an interest it should be able to recover the missed event from any of the broker nodes in the system. Removing the restriction of clients reconnecting back to the same broker that it was last attached to and the departure from the time-bound failure recovery model, leads to a situation where brokers could be dynamically instantiated based on the concentration of clients.
