You don’t need the “perfect Rails architecture.” You need 100 deploys this month. Speed creates feedback. Feedback creates money. Volume beats perfection. Every time.
This is one of the things I’ve been doing at Cursor! We’ve migrated our largest database workload, the `codebase` cluster, from AWS Aurora Limitless to PlanetScale. The cluster contains syncing metadata for all the user codebases that we index. Why did we migrate from Aurora…

PlanetScale is a beast. Our largest workload there has 256 shards and 300 TB (!) of data. Queries respond at ~10ms (p99) at peak hours. Just bonkers.

One thing that has served me well over and over in my career is just betting on software / services from people i like. @isamlambert is rad and @PlanetScale is no exception… moving to planetscale has been a revelation. Also i got this cool hat i can annoy my team with
A good run is like a bandaid. Gives you just enough life for the next few hours to mutter a “we’re back”.
This is a very unique opportunity to work in a leading database startup. Hard to overstate how far ahead of the competition PlanetScale is right now.

Seems like everyone's talking about database sharding. Earlier this year, I wrote an interactive guide on how it works for relational databases. Every engineer should know the core principles and challenges of sharding. This article is here to help.
We’ve been hard at work building the most scalable and reliable sharding solution for Postgres. A great piece of software deserves a great name and iconography. Say hello to Neki.
