Publish Subscribe Channel
- JMS for working with JMS Topics for high performance, clustering and load balancing
- XMPP when using rooms for group communication
- SEDA for working with SEDA in the same CamelContext which can work in pub-sub, but allowing multiple consumers.
- VM as SEDA but for intra-JVM.
Using Routing Logic
Another option is to explicitly list the publish-subscribe relationship in your routing logic; this keeps the producer and consumer decoupled but lets you control the fine grained routing configuration using the DSL or Xml Configuration.
