There are six message types within Diffusion:
- Broadcast message
- Exclusive Broadcast message
- Group Broadcast message
- Private message
- Priority message
- Client message
Broadcast message
A broadcast message is the most common message type. A broadcast message is sent to all the clients on a given topic.
Exclusive Broadcast message
An exclusive broadcast message is sent to all clients except for one on a given topic. For example, should a client publish a message to Diffusion for general broadcast there is little point sending this back to the sender.
Group Broadcast message
A group broadcast message is a message sent to a given group of clients on a given topic.
Private message
Private message is a message sent to one client on a given topic.
Priority message
Priority message allows you to publish a message, which will jump to the front of each client’s queue. For example, you may want to send a broadcast message to all the clients to inform them that the application or business may be temporarily closing or shutting down and finish off what they are doing by a given time. You may want to warn a client that their roundtrip/connectivity is very poor, the high water mark in their queue has been broken and it is worth their while contacting their local support team.
Client message
A message sent from the client down a given topic to the Diffusion server. This message can then either be served as a request to your application server (i.e. place an order, logon etc.) or published to other connected clients (i.e. a forum, twitter etc.).
