AI Writes Code Faster Than Uber Can Merge It - Preetam Dwivedi & Manjari Akella, Uber
AI Engineer — Nov 9, 2026 — conference
Why watch
Uber engineers share how AI-driven code changes at scale (5,000+ developers, tens of thousands of commits weekly) overwhelmed their merge pipeline and the three SubmitQueue innovations they built to solve it: admission gating to prioritize cheap changes, deferral queue to soften developer impact, and conflict relaxation for parallel execution. The talk covers post-commit Stovepipe checks and Uber's shift from always-green trunk to hybrid approach. Essential viewing for platform and developer productivity engineers.
