3.9. Bridges and routing
Some messaging systems allow isolated clusters or single nodes to be bridged together, typically over unreliable connections like a wide area network (WAN), or the Internet.
A bridge normally consumes messages from a queue on one server and routes messages to another queue on a different server. Bridges cope with unreliable connections, automatically reconnecting when the connection is available again.
HornetQ bridges can be configured with filter expressions to only forward certain messages, and transformation can also be hooked in.
HornetQ also allows routing between queues to be configured in server side configuration. This allows complex routing networks to be set up forwarding or copying messages from one destination to another, forming a global network of interconnected brokers.
For more information refer to Chapter 34, Core Bridges and Chapter 33, Diverting and Splitting Message Flows.
