Buck2: Optimization & Dynamic Dependencies (Neil Mitchell, Chris Hopman @ Meta) - Oct 2023

In this presentation, Neil Mitchell and Chris Hopman from Meta introduce the primary build system used by developers at Meta: Buck2. This open source solution is polyglot and specifically optimized for monorepos. And it's performance is reportedly double that of its predecessor, Buck1.
Throughout the presentation, Neil and Chris highlight several features of Buck2. It uses target files written in Starklark and Starklark-based rules, a core binary written in Rust, along with built-in tools such as linting, profiling, and a type checker.
The focus of Buck2's development was speed, resulting in a streamlined dependency graph, support for remote execution, and more efficient virtual file handling. They noted that some rules are still in work and that Buck2 currently lacks a bzlmod-like packagemanager. But, the build system does include the new BXL (Buck Extension Language).
