That was a good read, thanks!

it uses a single file on disk as a backing store

While this is the norm, you can have one database in multiple files.

Also, provides benchmarks on a file-based database whithout providing any details on the underlying filesystem.

I use SQLite to power up lots of stuff I’m working on. It’s lightweight, fast, simple and well-documented for small projects — like a Postgres but very local. Saves me from having to deal with containers “just to store data”, let alone for moving stuff to other machine where I would also need the permissions to configure and run containers in the first place; whereas all you need to pass SQLite databases along is scp / rsync.

It’s an interesting format for passing around information that’s best structured as a database, thus useful for one of my current spare-time projects.
