Very much not new. Nobody's done it for MySQL yet to my knowledge though, and I don't think many have looked at the implications of log-structured storage on SSDs. That kind of storage is notoriously difficult to do cleanly on a rotational drive, but our indexing scheme is quite simple. It's essentially some combination of shadow paging and side-effect-free style from the functional programming world, if that makes any sense to you.
