public class HotColdFailoverKrouter<T extends HotColdFailoverKrouter>
extends SingleActiveServiceKrouter<T>

Simple HotCold failover router - several service instances might connect, but only first one is used (as long it is connected). Once this instance disconnect, the next one is used. Note that implementing routing (+tweaks) require to break idiomatic concurrency handling of kontraktor, anyway this is not visible to outer world.
