What's the logical difference between having object data in memory on a
memcache server and having it in page cache on an object server?
+1 - about a syscall - i.e. not much - I think memcache does it's own heap

I guess that is an excellent answer on why does swift explicitly disable
object data caching at the page cache level. But my question is a bit
different Why doesn't swift use memcached

Hi,
I have noticed that even though account/container information is
cached using memcached in Swift, it doesn't cache any actual object
data.
Could someone enlighten me what's the consideration behind this
decision? Because it seems like it might be useful...
Thanks a lot

You're right. Caching object data is one way to really speed up reads to
content that is stored in Swift and accessed frequently. Often time, deployers
use existing tools like squid, varnish, or a CDN to do that.
But that still leaves the question why don't we cache the object data in
Swift?.
Thanks a lot for your answer.

it is a bit different than implementing it yourself
