Follow a SQL query through the router, across four Postgres shards, and back.
Every language pitches async/await as synchronous-looking code, and the same two keywords appear everywhere. But behind the shared syntax hide nine independent design decisions, and no two of seven modern runtimes agree on what even the simplest async programs should do! In this paper we map the design space of async/await so you can find out where your language stands.
Five Rust-level memory optimizations to the DNS cache layout of Big Pineapple cut per-entry memory by 56%, freeing approximately 100 TB of memory across Cloudflare's fleet.

Zak van der Merwe has spent his entire career at AWS building control planes. First for EC2 and now for DSQL. On the surface, the control plane looks quite boring: it records what should exist and reconciles that with what actually does. Nobody leaves school dreaming of building one, but Zak will be the first to tell you that if you like solving hard problems in distributed systems, there are few better places to be. It’s where many of those hard problems converge, and where the decisions you make determine whether a service survives its own growth.
