Hello everyone,
I have bumped into an article from one of the memcached creators where
he discuss the use of memcached to store session data:
http://dormando.livejournal.com/495593.html
Maybe we need to take it into consideration. Maybe it'll bring more
problems than solutions for a future, scallable HA environment.
Best regards,

SQLite doesn't introduce any additional dependencies, memcached requires
installation of memcached (admittedly it's not hard on most distros, but it
*is* yet another step) and in most cases the installation of another python
module to interface with it.
Memcached might be a good choice for devstack, but it may or may not be the
right thing to recommend for Horizon by default.

memcache can be distributed (so usable in HA) and has far better
performances then db sessions.
Why not use memcache by default?
I guess for the simple reason that if you restart your memcache you
loose all the sessions?
Indeed, and for devstack that's an easy way do do a cleanup of old sessions :-)
We are well talking about devstack in this thread, where loosing sessions after
a memcache restart is not an issue and looks more like a very handy feature.
For production it's another mater, and operators have the choice.
