Demo Subscriber is designed to demonstrate (in conjunction with the Demo Feed Handler) how messages flow through RAP.
Demo Subscriber receives messages from publishers and either writes the messages to a file or discards them (depending on configuration). The Demo Subscriber is not required in a production environment.
The Demo Subscriber receives messages from publishers on multiple data streams. You decide how the Demo Subscriber behaves.
Each data stream listens for packets on one UDP broadcast channel. When a packet arrives, the Demo Subscriber will either write the messages to a file or discard the messages, depending on how the Demo Subscriber is configured.
