This is a cool project, and really well presented. I've looked doing similar, trying to query a large dataset through ranged lookups on a static file server in the past. I ran into issue of some hosters not providing support for ranged lookups. Or the CDNs I was using having behaviour like they only fetch the origin data source in 8MB blocks meaning there was quite a lot of latency when doing lots of small reads across a massive file. It would have been interesting to find out a bit more about these topics, and see a bit more on performance.
