2 Hours to 10 Minutes: Building Rust Monorepos at Scale with Bazel RBE

Thursday September 10, 2026 13:45 - 14:25 EDT

Palais des Congrès de Montréal

A Rust monorepo with multiple workspaces and a CI pipeline that routinely exceeded two hours with recurrent flaky results. After five iterations — GitHub Actions tuning, shell script hacks, self-hosted Prow and a custom Rust-based orchestrator — each improvement eventually hit a ceiling, until the team spent more time debugging CI than shipping code.

This talk is about the infrastructure that broke the cycle: Bazel Remote Build Execution on self-hosted bare metal, bringing CI under ten minutes. Engineers can choose to use Cargo or Bazel locally — no workflow disruption.

The talk walks through what was built, why each previous approach hit its ceiling, and what running an RBE cluster for Rust actually looks like in production.
