A bit off topic, but any book/article recommendations for building things at Twitter/IG scale? I know for example IG switched to a "fan-out" approach early on to handle accounts with a lot of users. Would love to learn more about this.

In some previous HN thread, I dialed in on a recommendation for "Designing Data-Intensive Applications" by Martin Kleppmann, which I honestly still haven't gotten around to reading so....YMMV. Maybe if you search HN for that book title, it might lead you to other useful discussions?
