Durable Subscriber

Camel supports the Durable Subscriber from the EIP patterns book.

Camel supports the Durable Subscriber from the EIP patterns using components, such as the JMS or Kafka component, which supports publish & subscribe using topics with support for non-durable and durable subscribers.

Example

Here is a simple example of creating durable subscribers to a JMS topic

Using Java DSL

from("direct:start")
  .to("activemq:topic:foo");

from("activemq:topic:foo?clientId=1&durableSubscriptionName=bar1")
  .to("mock:result1");

from("activemq:topic:foo?clientId=2&durableSubscriptionName=bar2")
  .to("mock:result2");

Using XML DSL

<routes>
    <route>
        <from uri="direct:start"/>
        <to uri="activemq:topic:foo"/>
    </route>

    <route>
        <from uri="activemq:topic:foo?clientId=1&amp;durableSubscriptionName=bar1"/>
        <to uri="mock:result1"/>
    </route>

    <route>
        <from uri="activemq:topic:foo?clientId=2&amp;durableSubscriptionName=bar2"/>
        <to uri="mock:result2"/>
    </route>
</routes>
