@jalefkowit Your post reminds me of exactly why I don't like the ideology of scalability™, as if you could take a thing and use it at any scale, which is a trap.

Software doesn't needs a database as long as what's needed to be parsed (so static files excluded) can fit into RAM and other kind of upper limits like storage latency.
And a database is something that itself needs maintenance and special software (in-database data typically being non-portable, eww) with added complexity to use it, so it's seriously worth it to just plainly avoid it.
