Don't tell HackerNews but my new feature serves millions of users with p99s of around 400 microseconds
The new feature is Social Proof, coming soon (people you follow who also follow N, etc.)
Also if you want to know how I built this, I blogged about a bit of it here - jazco.dev/2024/04/20/r...
this makes no sense. it's the wrong tool for the job. you want to be using a sparse adjacency matrix to store your data, and then operate on it. will be orders of magnitude faster than this.
(For those out of the loop Hailey is copypastaing a comment from when my blog went viral on HN a month ago and people decided to tell me how I was Doing It Wrong)
