Just so sad that Vertica is proprietary so we can't see how they did it! ;)
On a serious note: Please check out EventQL [0] some time. It's very similar to Vertica in some ways and completely open-source. It's a new project (beta) and not nearly as mature as vertica yet though (still a long way to go).
