dynamically on Kubernetes

   Regarding using Deployment for instead of Pod, I generally agree but I think 
we need one consideration.
   
   Some interpreters (like markdown, jdbc) are stateless. So Pod can silently 
re-create.
   However stateful interpreters, like Spark, Python, when Pod is re-created, 
it loses all states and users need to know about it.
   
   So, unless we have some mechanism to notify user about Pod re-creation, I 
think it is not a bad idea to let Pod disappear and let the user get an error 
message about that.
   
   What do you think?
