Hi Melissa, It's likely your data is simply being evicted as not worth the memory it takes up - you can fit a lot of smaller memcache values in the space a blob takes up.
Consider just setting the correct caching headers in your response, instead. This will result in frontends, proxies and browsers caching your content, without using up precious memcache space. -Nick Johnson On Fri, Nov 4, 2011 at 3:32 PM, Melissa Hong <carra.mel...@gmail.com> wrote: > Hi, > > I just installed appstats and noticed that I'm hitting the database > for images all the time instead of the cache. > > In my image server I pull the image data from the blobstore to serve > and use memcache to store the blob data for later use. > > Using logging, I've determined that it is setting the memcache with > the image data, but the next time I go to grab this image memcache > returns None. > > My theories are: > 1.
