Open Stack

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.

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.
