The problem with the OP article is that it’s a tiny toy:

> “Three tables: Publisher -> Author -> Book. Seeded with 4,215 real books from the Open Library API: Agatha Christie, Dostoevsky, Penguin Books, real data with real-world cardinality.”

What “real-world” application is that tiny? You could keep this all in RAM on a machine with say 16 MB or so of RAM (not GB!) A Raspberry Pi would be overkill.

The lesson from the article is, a framework doesn’t matter if your scale is below the mom-and-pop shop level.
