They're not one that I'd say is "all the rage" - two reasons: MySQL doesn't
work for DW queries and more importantly doing a different storage engine
doesn't solve the DW performance and scale problems.

WRT "all the rage" - you'd have to point to more than press releases about
technology to make that case. We've beaten the "all the rage" companies in
every POC so far and I haven't seen or heard of significant reference
installations.
