Shouldn't lots of redundancy be a fundamental part of which ever db you are using.

As to extreme do-normalization, colour me sceptical, why not parallelise and throw more hardware at the problem?

Because it's more cost effective to de-normalize then to parallelise in this instance.

Turns out it's difficult to parallelize without also denormalizing...
