   > Agree with your "bad data better than to lose all data" theory.
   > 
   > My question is, if we always keep the "bad data", for example, if we don't destroy all invokers when receive an empty url list, when should we clear all invokers, shouldn't there be another signal? In some scenarios, e.g., Graceful Shutdown, Offline, we need to destroy all invokers.
   
   I think we can keep bad data, call it in the original way, destroy the caller, in the Provider there is a readonly mechanism to end the caller, or gracefully go offline to end the caller, and the life cycle of the caller should not be over Controlled by the data in the registry
