This looks pretty cool.<p>On the downside it can't do aggregates, it can't do query filters on more than one property, it can't do joins, it has its own unique query language, and it is a proprietary system with no chance of moving to another provider or hosting it yourself.<p>Speaking of it having its own query language, perhaps that isn't a big deal given you can't do any non-trivial queries.<p>For me, the pejorative NoSQL claim is actually a marketing turn off.
