   An activation once pulled from the kafka bus in an invoker may be lost (or executed but an activation record lost) if an invoker fails, or the connection to couch fails. The execution of an action is best effort, at most once.
   
   The idea of having invoker pools for blocking vs non-blocking requests has been discussed in the past. There?s an ongoing work thread to modify the load balancing to allow work redistribution which is difficult to do today. Once in place - along with a fairness policy - it should be easier to have different pools scheduled. 
   
   If you want to do it today, you can follow the model used to segerate docker actions from other actions in the load balancer.
