All of these "fast" databases have a fatal flaw - it takes forever to load the data in the first place. In this case loading takes >1000x longer than the query so loading is all that matters.
Your complaint only makes sense if you only intend to perform one single query against a dataset.
The response time is quite fantastic (less than a minute), but there are drawbacks: - GC takes in the order of minutes to complete - loading the data takes 90 min from spinning rust
So yeah, it's possible, but your bottleneck becomes the storage driver.

Heavy fixed processing costs up front with the benefit of light variable processing moving forward.
It's far from the correct title. A good part of the optimisation of all modern analysis DBs is in-memory... this is no different and as such he's compared his work against 2 of the major other systems in the space.
I see a lot of critics here... I think the guy should be congratulated for his work - which if you've read through all pages, appears to be done single handed!
There's a lot more to data analysis than loading data off disk.
