This component can be used when you need dynamic discovery of endpoints in the Registry where you can compute the URI at runtime. Then you can look up the endpoint using the following code:

// look up endpoint
String myEndpointRef = "bigspenderOrder";
Endpoint endpoint = context.getEndpoint("ref:" + myEndpointRef);
   
Producer producer = endpoint.createProducer();
Exchange exchange = producer.createExchange();
exchange.getIn().setBody(payloadToSend);

// send the exchange
producer.process(exchange);
...

And you could have a list of endpoints defined in the Registry such as:

<camelContext id="camel" 
   xmlns="http://activemq.apache.org/camel/schema/spring">
   <endpoint id="normalOrder" uri="activemq:order.slow"/>
   <endpoint id="bigspenderOrder" uri="activemq:order.high"/>
   ...
</camelContext>
