Beaker can use SQLAlchemy or memcached as its backends.
Unfortunately we don't have a tutorial on how to set this up. Someone
wrote a good little intro that covers the Beaker backends here
(unfortunately he never migrated this over to the Beaker section on
the wiki):
http://www.openvest.com/trac/wiki/BeakerCache
It only covers just the Beaker API though, it doesn't cover how you'd
utilize these backends within Pylons. I think the key thing you need
to know is that you can set Beaker options (like the 'type' option) in
the app section of your ini file. e.g.:
beaker.type = 'memcached:stuff':
Those options are covered here:
http://wiki.pylonshq.com/display/beaker/Configuration+Options
The @beaker_cache decorator can also take a type argument.
