2010/1/8 nicanor.babula <nicanor.bab...@gmail.com <mailto:nicanor.bab...@gmail.com>>Hi everyone. How memcache works on GAE? Let me explain: Do I get one memcache instance per app instance or there is one memcache instance for all instastances of my app? one instance for all app instances.
so if one app instance does:
memcacheService.put("loggedUser", userData1);
and later another app instance does:
(UserData) memcacheService.get("loggedUser");
The latter instance will get the same data that the first instance put?
My app uses google accounts to handle users. I am thinking that it
might be faster reading the current user data from the memcache
instead of calling userService.getCurrentUser(). It would be a good
approach?
no! memcache data is not persistent, your memcache data could be
removed any time for any reason, like limited memory, cache age, etc.
I suggest you to go through docs.
I don't want to use it for persistence. I use the datastore for persistence.Once a user logs in I want to write to the memcache the logged user data in order to read it later (during one login session).
Thanks,
Cristian.
