I have no proof, but I think Edge cache is X size for all of Google. And When Google Traffic goes up, your app gets less edgecache. This is conjecture. But based on how I would design a system, and what I have seen of the way it works... I think that they can't give you a spec because you are pooled with all of Google.
I also think that my MS vs HR is similar, they don't reside on quite the same infrastructure and some app that also MS "buys" me priority in the Cache Tier System. Again Conjecture based on what I can see on each side of several black boxes. -----Original Message----- From: [email protected] [mailto:google-appengine@ groups.com] On Behalf Of Jeff Schnitzer Sent: Friday, September 16, 2011 11:29 AM To: [email protected] Subject: Re: [google-appengine] Re: Status of edge cache?

Sure, but when designing our apps we really need to know a rough idea what to expect from each caching layer. App design for "memcache clears every 30 seconds" will be different from "memcache clears every 5 days". I too would like to have better understanding of edge cache behavior. So far the only real documentation is Brandon's experimental observations. I don't need rigid guarantees, I just want a rough idea what to expect.
