I really liked that 2/3 of the post is a walk through the solutions using existing tools before getting to the project.

I also like how it combines a "big data" format (parquet) with the main "your data isn't actually big data" tool of choice (sqlite).

Yes as a demonstration of a good expository post I rate this as 100% of what I looking for.
