It can be dropped in, but it silently ignores expiration times. It's a
data store, not a cache. Beware of that. If you rely on expiration for
regenerating cache, you won't get it with TT.

If you need to keep items around, then you need to make special
considerations, like making sure you have plenty of spare memory or
having separate memcache servers for all the expire=0 items, but
honestly you should probably take a look at a persistent key-value store
instead, since that is exactly what they're designed to do.
TokyoTyrant, for example, does this and even speaks the memcached
protocol (not sure if the same is true for KyotoDystopia), so it can
just be dropped in.

Hi-
Is there a setting where memcached will log when it deletes a cache
entry to make space for an incoming entry? I am running with -vv and
so far have not seen any such logs entries, but maybe I am missing
it. Reason I'm asking is I am storing some data with expire = 0, and
some time later when I ask for that data, its not there. Only reason
I can think of is that its being kicked out to make room for other
things.
Thanks!
