Ask HN: What database does HN use?

6 points by ghd_ 2 days ago

A similar discussion from 2021 that didn't track a lot of attention: https://news.ycombinator.com/item?id=29165586

And the only answer from eesmith cites a very old implementation, I'm wondering what's being used nowadays in the HN code base

Every discussion I've seen mentions filesystem-based storage rather than any database. Haven't seen any evidence to the contrary.

They have a job listing looking for engineers. I have no idea if this role would work on HN or if the tech stack is relevant to HN.

It lists the tech stack as Rails, React, Postgres.

HN is not written in React or Rails. It is written in a LISP dialect called Arc.

I think hackernews was originally built with a Lisp language right?!

If so, probably started with a database that you would commonly pair with a Lisp language
