TokioConf T-Shirt
We are 3 weeks out from the first @tokioconf.com. Spoiler: This is the t-shirt! I just saw the design and had to share it. It is so exciting to see it all come together. You still have time to get tickets, but not much time! tokioconf.com.
I finally published Toasty (async Rust ORM) crates! I’ll be writing about it soon (and why it took so long). github.com/tokio-rs/toa...
We're setting aside 20 free TokioConf tickets for contributors and open source maintainers. If you've submitted a PR to any tokio-rs, hyperium, or tower-rs repo, that's you. Know someone who qualifies? Send them our way! tokio.rs/blog/2026-03...
I will also be at Tokio Conf next month! Really looking forward to meeting more folk working on and with Tokio.
There’s some great talks scheduled, including one by my colleague Pooja Kale on how DSQL uses Tokio in its control plane
Great blog from Russell Cohen on dial9. I saw a demo of this recently and it is very cool. Exactly the visibility that’s been missing for Tokio

You can think of it like the execution time of a lambda, which for the same code will vary across executions. The average will be stable, but there will be some amount of variation
The compute DPU part is kind of intrinsically variable. We do have bounds on the variability but there will always be some amount that the compute time can vary due to nondeterminism in execution time, vs bytes read or written which will be stable across the same query.
This blog from Marc Bowes is a great starter on DSQL pricing: marc-bowes.com/dsql-how-to-...
The tldr is it’s very cheap for small projects
DSQL just launched support for SEQUENCES and IDENTITY columns. It’s exciting seeing the team launch new features the same week we became available in four new regions.
I wrote a short blog about how we make sure they scale here: blog.benjscho.dev/technical/20...
The cost of turning written business logic into code has dropped to zero. At best, near-zero.
The cost of integrating services and libraries, the plumbing of the code world, has dropped to zero. At best, near-zero.
What does that mean for the future?

Bernardo as well, he’s great, used to run Amazons internal Rust build system
Blaring ads on gas pumps are the peak of American culture
This sounds great, we have a skill integration that you might find useful!

We introduce LeaseGuard: a Raft-specific lease protocol with a precise spec and fast recovery after crashes.
Paper + Implementation linked in our joint (w Jesse @emptysqua.re) blog post below.

TIL (thanks to this paper) that common 64-bit systems are only using 48-bits of that to actually address memory. Still leaving a cool 256TB max addressable size
The Bf-tree paper from VLDB ‘24 looks neat, it’s a shame the implementation hasn’t been released yet. Maybe a chance for someone Christmas tinkering

Zig’s fun, I like the explicit error handling and fast compile times. I struggled a bit getting some of the simpler things set up, like reading from a file, mainly because the documentation is lacking in examples for the latest version

🆕 Here is my latest blog introducing a Serverless Multi-Region E-Commerce Platform based on an Amazon Aurora DSQL database. For a database platform I have almost always used DynamoDB due to it being truly serverless and pay as you go. (1️⃣/4️⃣)

My demo from the Amazon Aurora livestream is now up as a VOD on YouTube, you can catch it here: youtu.be/5iFA_7lo9aI?...
What are the best languages for multiprocessor programming right now? Thinking ones that provide strong, safe primitives and good performance.
I know Rust works well for this thanks to ownership & releasing of locks on drop. Are there any others that are worth trying?
I’ve been blowing through Octavia Butler’s Patternists series over the past few weeks. Love how each of them threads together while standing completely on its own.
This blog post from Marc Bowes might help with understanding pricing: marc-bowes.com/dsql-how-to-...
People always ask me “so is AWS using Rust?” Happy to be part of this article shining some light on how Rust is changing the way services are built in AWS.
In a new guest post from #AWS Sr. Principal Engineers @nikomatsakis.com and Mark Bowes take us inside Aurora DSQL's development from scaling write operations without two-phase commit, to overcoming garbage collection hurdles, and embracing Rust. www.allthingsdistributed.com/2025/05/just...
Very glad Steve didn’t follow this advice and that the Rust book exists, it’s an incredible resource
Writing about something you don’t know is often the best way to _start knowing_
I love this paper! It’s a clear way to communicate that both application and infra developers are responsible for how to make things scalable, while splitting those responsibilities neatly
By taking the time to encode some safety property in the type system, you save yourself time and pain down the line in explaining how to use it or preventing misuse
Wrote a short bit about Rust being a “Safe for X” language: blog.benjscho.dev/technical/20...
I’ve basically had this article from lwn in my head for a while and it’s a major reason why I love working in Rust, especially on a big project with a lot of other engineers
Not sure how popular it'll be but I thought this one was pretty good.
