> If your business model implies a scale-or-die condition, then I'd say it's fair to design your solution to accommodate NoSQL, but not waste time implementing it in production. It's a horrible waste of time to design something around a Cassandra cluster that will be hit once every second.

It sounded to me like he was saying that sometimes it's actually more work to figure out how to stuff your data into a relational db than a non-relational one?
