Faster continuous integration builds at Canva

How we improved our continuous integration build times from hours to less than 30 minutes.

Is hard to migrate builds and tests into because you must declare every input that a rule depends on, which requires a significant amount of time, effort, and some Bazel-specific knowledge. The reliability of the new E2E framework also significantly improved over the previous iteration because each service container is hermetically tested in isolation, making failures much easier to detect and diagnose. These projects or launches might not have had a large or direct impact on build times because they weren’t on the critical path, but they still improved the CI DX by making the pass or fail signals of these steps faster.
