Load balancing in Camel

[Nivetha Shri <ni...@gmail.com>]

Hi All
I want to know how we can combine dynamic routing and load balancing.

For dynamic routing am using @RecipientList annotation as follows

public class RoutingComponent{
    @RecipientList
    public String[] route(String Body) {
  String output = "activemq1:topic:topic.outbound";
return new String[] {output};
    }
}

And my RouterBuilder configuration is as follows:

from("activemq1:topic:topic.inbound").bean(RoutingComponent.class, "route");

In general it is given that load balancing can be achieved as

from("activemq1:topic:topic.inbound").loadBalance().roundRobin("outputqueue1","outputqueue2");

But how can we achieve it using @RecipientList?

Any insight on this will be really helpful

Thanks and Regards
Nivi

Well using @RecipientList aka Dynamic Recipient EIP pattern, then its
YOU that are responsible for providing the endpoint(s) that should
receive the same message.

So you can implement your own round robin implementation in the code
and return a different endpoint on each invocation.

I need to think a bit more if/how you can use @RecipientList with
Camels load balancer directly. But its an interesting use case to be
able to support.
