I want the next Hacking SaaS to focus on UUIDs a bit. Pros, cons, when to use, which to use, how to use, etc. Links to high quality UUID-related resources will be appreciated.

Here are some links I liked! I assume you mainly mean UUIDs for Primary Keys and not UUIDs in other use cases like for external identifiers? • Haki Benita “Unconventional ways to index UUIDs in PostgreSQL | Citus Con: An Event for Postgres 2023” • Going deep on UUIDs and ULIDs https://www.honeybadger.io/blog/uuids-and-ulids/ • UUIDs vs Serial for Primary Keys - what’s the right choice? https://pganalyze.com/blog/5mins-postgres-uuid-vs-serial-primary-keys

Great stuff! Thank you!

This one is old but related to the same topic mainly why not to use UUIDs https://instagram-engineering.com/sharding-ids-at-instagram-1cf5a71e5a5c https://abheist.com/twitter-snowflake-for-unique-ids/

Thanks, Lalit. I was looking at Snowflake last week. It is interesting, but I don't think it does anything more thank ULID / UUIDv7? Unless I missed something important...

Oh I have outdated knowledge. First time hearing about ULID. Actually I have stopped following UUID after UUIDv4 😅

See, thats why I'm writing a newsletter 🙂 So we can all get up to speed with the important solutions in an area...

Finally Hacking SaaS arrived 👏
