Memcache can empty at any moment. It is not to be used for anything other than cache.
you can do a set in one line and get in the next line and have the value be not found. From: [email protected] [mailto:[email protected]] On Behalf Of Tom Saulpaugh Sent: Tuesday, September 25, 2012 3:48 PM To: [email protected] Subject: [google-appengine] Memcache seems to be cleared periodically I've been observing our production system memcache stats today and noticed that the oldest object in the cache is only 7 minutes old. On our test system, running the same code, the oldest object is over 4 hours old. On our production system, I saw today at least 3 times where the oldest aged object would get up to as high as 33 minutes but then fall back to 1 minute or so. We are using Objectify to set the cache expiration time for our entity objects. These times range from 10 minutes to 2 hours. Are there any known conditions where memcache is cleared due to errors or quotas? (or something else?). Has anyone else seen this behavior?
