[wildfly-dev] Allow Camel LoadBalancer to connect to clustered WildFly HTTP endpoints

[Thomas Diesler]

Zookeeper is part of the Fabric architecture. I may be an option in the context of this conversation, but its not something that we have already readily available.

In the most simplistic scenario, we have a remote Camel Http client that wants to connect to cluster of wildfly servers that expose undertow endpoints. The Camel client wants to use a load balancer <http://camel.apache.org/load-balancer.html> like this

<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
  <route>
    <from uri="direct:start"/>
    <loadBalance>        
        <roundRobin/>
        <to uri="mock:x"/>        
        <to uri="mock:y"/>       
        <to uri="mock:z"/>                 
    </loadBalance>
  </route>
</camelContext> 

I now wonder if it is possible to implement a camel load balancer variant that is able to discover the initial topology of wildfly http endpoints and later react on changes in that topology. Does that make sense?

cheers
