I'm interested in this, too.

I can totally see how not having to manage a standalone RDBMS makes sense. But, what's the real-world advantage over something like SQLite?

I mean, the idea of an in-memory relational engine for things like games or embedded totally makes sense, but this seems to target large datasets and deep analysis.

As far as I understand with this model you pretty much re-ingest data from the "raw" source on startup every time. Is this correct?

Judging by the rise on interest I'm sure there's an obvious use case I'm not seeing either.
