I see it the other way because I need something to serve out key-value
data fast. And memcached is the answer when it comes to utilizing the
full memory available, and serving it out fast. Just that I wanted one
more layer that keeps the data persistent.

You may look at it as having written a mysql layer first and then put
the memcached on top of it. But think about it, if memcached did have
a persistent option as well(along with all its current properties),
you would not have gone to mysql for many apps!

Just a different point of view. You can rightly argue that its not
what memcached is meant to do, but then this is just an item in my


"Reality is merely an illusion, albeit a very persistent one."
