Does appengine do this in a way which is safe to a heavily-loaded application? i.e. load the new instance while the old instance is still serving requests and then simply re-direct requests to the new instance?
Something like this should really be documented.

Application instances are meant to be relatively short lived. Once each instance has served a certain amount of requests, we will gracefully terminate it and spin up a new instance to take its place. The number of requests to trigger this limit is subject to change for performance tuning reasons, but it should be in the ballpark of tens of thousands of requests. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com <http://googleappengine.blogspot.com/> Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Wed, Oct 27, 2010 at 1:50 PM, nickmilon <nickmi...@gmail.com> wrote: I was doing some load tests on app engine today when I noticed a new Info message in the logs: "After handling this request, the process that handled this request reached the maximum number of requests that may be handled in a single process' lifetime, and exited normally." So what that supposed to mean ? Up to know we new that application instances are automatically terminated after some inactivity time out. If I understand this message well now we know that a process can be terminated after handling so many requests. How many exactly ? is this a new magic number ? Lets hope we will have some answers from the always helpful App Engines team. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
