GitHub has unveiled a next-generation Git storage architecture designed to support thousands of concurrent agents and 7,200 pushes per second. Built to scale for agentic development, the system decouples storage from compute and minimizes coordination. Only reference updates require agreement, allowing independent scaling of data storage, request serving, and repository maintenance.
The architecture handles massive read fan-out from CI, deployments, and other agents fetching new commits. Targeting two orders of magnitude more scale, it supports multiple writer nodes and processes large writes efficiently. Developers experience no change in workflow—push, fetch, and branch as before—with full protections intact.
The system is already live, powering GitHub's platform beneath the surface.
