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?

I am thinking that you could register undertow subsystem event listeners in camel subsystem (or any other that is for that purpase)

So undertow subsystem would send you events on when deployments are started/stopped, hosts are started/stopped.

see https://github.com/wildfly/wildfly/blob/master/undertow/src/main/java/org/wildfly/extension/undertow/UndertowEventListener.java for what is possible

This is how we integrate with mod_cluster subsystem that than broadcasts the config to the apache mod_cluster module.

You could get this events and than push config to zookeeper based on that.

would that work for you?
