How do you make 768 servers look like 1? The answer is sharding. I wrote about *why* it's needed and *how* it's achieved for Postgres and MySQL. It's a fun one. Link below.

You asked for it, so here it is. Visualizing CPU cache speeds relative to RAM. Cache optimization is important too!

S3 transitioned from eventual consistency to strong consistency. No downtime required, across exabytes of data. "if something happens only once in a billion requests, that means it happens multiple times per day within S3" Werner has a great article on the process (link below)

Been working on this for 2 months, and it's finally ready to share! This piece not only *describes* how B-trees and database indexes work, but gives you the opportunity to interact with them, reinforcing the concepts, and providing a bit of fun along the way. Link in thread.

Fast backups at-scale are made possible by sharding. These require an amazing amount of engineering to nail the infrastructure, orchestration, and reliability. I wrote all about it... with the help of some PlanetScale database geniuses, of course!

1 of N reasons why sharding is a great way to scale a database? Backup speed. This is one of the fun little animations I worked on in my recent interactive sharding article. In case you missed it, link below.

This is one of the best engineering blogs you'll ever read. Not *just* because you'll learn a lot, but because Vicent Martí sprinkles in a bit of everything. A great story. History of git infrastructure. Distributed systems. Benchmarks. All written by someone who can speak to every point from deep, personal experience. It's also 5,300 words, so grab a drink and enjoy.

Most of us don't have access to multi-million dollar NVIDIA gpu sleds (if you do, hit me up). But I wanted to learn how they work, so i build a 3d guide! Unified GPU / CPU systems like this are what's powering all these mega-ai DCs. Incredible what educational tools you can build with llms.

The Excalidraw mcp is sick. Have it live draw explanations (with pencil sounds and all) then pop open to the app and make your own changes. Learning with ai is so fun. (Also, don't stop learning, your brain is too valuable)

As a relative F1 noob, the rules around car construction were confusing. So I built a tool to teach me. Each part has restrictions on what teams can and cannot customize + what is and isn't proprietary, etc, etc. Hard to navigate for newcomers. A visual guide.

There's a million reasons why your app can be slow. The stack of software and hardware beneath are complex. Pinning down performance issues is challenging (but also, fun!) A clip from the chapter 1 stream. More to come this week.

Query planning is hard. Doing so in a massive, sharded database is even harder. The blog we published today at PlanetScale was a labor of love. So many people from across the company helped with technical accuracy, writing, visuals, and making it the best it can be. This was so much fun to be a part of. Go read. Get a little better at database query planners this evening.
