So it's an in-memory optimisation for the specific application, and not anything to do with the database at all. It's been done lots of times (not that specific thing, just the concept), and what usually happens is that in a few years database and hardware improvements catch up with the optimisation to the point where doing it is no longer worthwhile.

But it's off-topic for c.d.o.s.

There are people working with the idea of using column-wise storage for the physical layer of an RDBMS, but I doubt that any existing major product will change its entire disk-storage strategy anytime soon, so I guess that's off-topic here as well.
