> Lenton says Canonical has worked with "the company behind CouchDB" to make the database scale > in a particular way. "Our situation is rather unique and we were unable to resolve some of the issues > we came across," said Lenton, who pointed out they needed to scale to millions of users and scale > down to a "reasonable load on small client machines". Does anyone happen to know exactly what was the blocker(s) for Canonical? e.g. client load time for small mobile devices?
