Tuning your database just right can be counter-intuitive, unless you understand all levels of the system. Intuitively, most would say "more work_mem = better" for building indexes, but this hurts performance due to L3 cache behavior. Great article by Tomas Vondra. vondra.me/posts/dont-g...

I wonder what the Bitconnect guy is doing right now

TLDR: io_uring won't help much if treated as a drop-in replacement for existing database I/O architectures. Better performance will often require architectural changes. When applied, there's tons of performance gains to be had. Here's the paper: arxiv.org/pdf/2512.04859

I'm excited about the database performance io_uring will unlock. Last year I benchmarked Postgres 17 vs 18 to test the initial io_uring upgrades. I was surprised to see they weren't always a clear win for TPC-C. This paper studies the potential, and the future looks good.

This is the best article I've read on MVCC in MySQL. MySQL and Postgres use quite different engineering techniques are used to address the same problem. Undo log vs multiple tuple versions. Another great one by Jeremy Cole. blog.jcole.us/2014/04/16/t...

before I can truly relax for christmas I must face one of my longest held nemeses: glittery wrapping paper

Local NVMe avoids the network hop but requires more provisioned storage per host. You also need solid orchestration for backups and reliability. Different tradeoff, not wrong or right.

AWS Aurora convinced everyone that separating storage and compute is always the right architecture. People accept this as gospel. But it's just a design trade-off: accept network latency as your bottleneck in exchange for better storage utilization.

Curious about the benefits of version 18? A big one is upgraded I/O performance. We conducted benchmarks to show the improvements in action: planetscale.com/blog/benchma...

If you're in Berlin today, I'm doing my first ever market with my glass - at #Weddingmarkt Christmas Market on Leopoldplatz - from 11:00 - 19:00! (i'm... a lil terrified, but I did make a bunch of cute mini vases so....)

Some days I wish I had a more interactive code review tool than GitHub's. I'm looking over a PR for a pretty gnarly change in a C project and I want to write notes all over it that I reference later. I'm genuinely tempted to print the thing and go over it with a pen like a teacher.

Postgres uses TOAST to store large, variable-sized data values like JSONB and TEXT. Using it impacts performance, so you gotta know the tradeoffs.

For anyone waiting for the video: my #SREcon talk is now up! Lots of deep details in there about how hard it is to store data reliably and how tiny mistakes can turn into big problems.

How do Postgres and MySQL achieve data durability? Our very own Chris Sinjakli spoke at SREcon about how this works and the many engineering challenges it presents. Watch on YouTube: www.youtube.com/watch?v=bFGN...

PlanetScale Insights is amazing. Correlating schema/config changes and performance has never been easier. The perfect tool for squeezing every ounce of performance out of your database resources.
