Faster at some things :-). column oriented db is a tradeoff...it's
less work to get one or two columns but your record is not guaranteed
to be in one place on disk...which has obvious downsides. I don't
have any evidence other than my gut, but I betcha column db being an
'evolutionary step' above current methods is mostly hype. However for
certain workloads I'm sure it's great...
