FoundationDB, the Black Knight - Peter Boros, Tigris Data

Wednesday June 25, 2025 11:55am - 12:35pm MDT

Bluebird Ballroom 2G

Monty Python’s Black Knight is the opponent that couldn’t lose. Even after all of his limbs were cut off, he offered a draw: “it’s just a scratch.”

FoundationDB (FDB) is a distributed transactional key-value store that is very difficult to defeat just like the Black Knight. Open-sourced in 2018 after an acquisition by Apple, FDB was designed to be a common layer: almost all databases have a backing key-value store. Many have built on top of it including Snowflake, Adobe, & Datadog.

FDB got it right: transactions, distributed by default, and extreme reliability. Kyle Kingsbury (aphyr) the author of Jepsen series on distributed systems correctness, said: "haven't tested foundation in part because their testing appears to be waaaay more rigorous than mine."

We examine a FoundationDB cluster and try to disrupt its operations. Our attempts are informed by real world experience supporting a metadata service for billions of objects globally.

When we finally succeed, we show how backups and disaster recovery resurrect FDB. We’ll learn about highly resilient design patterns and operations. We have battle scars, and want to help others!

How To Put Swift in a Box: Container Images From Scratch With Swift Container Plugin - Euan Harris, Apple, Inc.

Wednesday June 25, 2025 3:05pm - 3:45pm MDT

Bluebird Ballroom 2G

Containers have changed how we build and run services. The days of FTPing a binary up to a server are gone, because our platforms expect to run containers. We build container images at every stage of development, whenever we want to test our services, and when we deploy them.

If container images are what we need, could our development tools help us build them? Yes, they can! In this talk, we'll take a container image apart, see what makes it tick, then put it back together again from first principles - all using Swift!

Swift is a high performance, memory-safe language which is ideal for server-side development. We will:

* download a container image, take it apart by hand and explore what’s inside;
* cross-compile a Swift service effortlessly to different Linux distributions, on x86 or ARM, statically or dynamically linked, from development environments on macOS or Linux;
* use Swift's pluggable build system to produce container images efficiently and automatically for every build;
* test the image.

Containers are a universal building block of modern services. Even if you're not yet using Swift, these ideas and principles also underpin your current build and deployment workflow.
