There are no guarantees with Memcache. Memcache can evict values whenever it wants to (mostly due to space pressures, but other reasons can cause Memcache to drop values as well). If you want Memcache to retain a value, you need to repeatedly access it; this hints to Memcache that this value is important and needs to be retained.
If you want long-term storage, you need to store to the datastore, Cloud SQL, Cloud Storage, etc. -Vinny On Thursday, September 27, 2012 4:04:07 AM UTC-5, tousif wrote: > > I have read in google docs about memcache eviction policy but i'm > frustrated to see some of memcache keys evicted every time within a day. > Where as i have given four days (time to live).
