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... merlin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
