Publish Subscribe Channel

Camel supports the Publish Subscribe Channel from the EIP patterns using for example the following components:

  • 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.
