public class SimpleKrouter extends SingleActiveServiceKrouter<SimpleKrouter>
a Krouter supporting dynamic replacement of a single service. For stateful service's, clients keep connected to the service instance they originally connected. Once this old service terminates they failover to the "current" service instance. THIS IS NOT A FAILOVER: if the primary (least recently connected) service goes down, no new service can connect ('service unavailable), however clients connected to a previous service instance will continue working. Use HotColdFailover for dynamic failover + dynamic replacement use cases. Use case: Replacement / Zero Downtime software update. In general its favourable to always use HotColdFailover instead of SimpleKrouter, as this also covers dynamic replacement. (SimpleKrouter's orinigal role was having a simple case for testing debugging).
