Technically, it is very interesting -- it uses Roaring Bitmaps under the hood and builds a query engine on it. So an easy way to think about it is that it maps categorical data into a giant compressible distributed bitmap.

I've been planning to see if I can (mis)use it as an OLAP replacement but I haven't had time to get to it.

You definitely can... the feature set keeps growing. We have multi-field filtered GROUP BY now. It's amazing to see how flexible Roaring Bitmaps can be!
