Walter's -- clients must be tolerant always. This mindset is
important when working on scalable distributed systems. But depending
on clients being so tolerant leads to being less friendly --
increasing the likelihood that they w
If a program gets a list from a remote server, then expects that list to be
accurate when they make calls based on it, well, my kindest thought is
“charmingly naive”. Really, that is just bad code that hasn’t broken yet.
That is true even if it gets a list from Zookeeper. Things change while you
Thanks for calling this out more explicitly; definitelyf worth discussing.

I'd go even a step further and say that users shoul
