Alright, I'm not sure we would be ready to switch then, this means that you have one huge single point of failure then? Since many operations depend on the database. Although I guess in theory we could run both mysql and postgresql, and only use postgresql for the baruwa specific things (so not bayes, awl etc) it's not ideal, so I think working on making mysql an option for baruwa would be a good move. > > 2/ It appears memcached is a requirement, but I can't find any information > about clustering memcached, so what happens in a baruwa cluster if 1 node > (and its local memcache) is down?

But we can't move to a system with several components that aren't redundant. > - Andrew > > -- > www.baruwa.org > > _______________________________________________ http://pledgie.com/campaigns/12056
