I tried to RTFM a bit on the topic and wasn't able to find what was needed - if someone with more App Engine experience could point me in the right direction that would be great!
I understand that any cloud computing environment needs to allow for dynamic allocation of computing resources - I am just looking to discover what some of the operating parameters are so I can avoid errors with my apps. My questions: - Regarding the behavior of regular python data structures: Assume I have an object (an instance of a class) in global memory (for performance reasons) which contains various fields holding values. How long will a single user's web requests hit the same instance of that object? Will multiple requests ever go to different 'cached' instances of that object or another instance of that in-memory data structure located on a different server? Do I need to anticipate requests coming from the same user going to different web servers that have independant cached versions of my application's data structures, simultaneously? - How much 'memory' or 'ram' (Regular python memory') can I consume via my python code... in the form of lists, Strings, dicts, etc. before I encounter an exception? Is the limit per-user-session or per- app? - I noticed from limited testing that there is at least a small semblance of a session... what is the token used to arrbitrate them? ie: does GAE use a browser cookie, the IP of the user - or a cookie containing the user id? (I want to make sure that I don't invalidate whatever the mechanic is, so I don't destroy the user's sessions) I'll try to keep searching documentation for some answers... if anyone can point me to any info in the right direction I *greatly* appreciate, in advance, all your help, - Sal --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
