Taming 40-Minute CI: Incremental Builds at Monorepo Scale
Day 1 · Wed, May 12 · 8:30–9:00Main Stage
Our monorepo CI took 40 minutes on a good day. This talk walks through how we cut it to 6 minutes with content-addressed caching, remote execution, and a test-selection model — including the two migrations that failed first. You'll leave with a decision framework for which incremental-build investments pay off at which repo sizes, and the graphs to convince your platform team. Updated: now includes 2026 benchmark data. This session now includes a live demo of remote build caching.
