Cursor explains Continuity, a WAL-based Git storage system
Git at any scale
AISummary
Cursor's blog describes Continuity, its Git storage system, which stores each push as a write-ahead log entry in S3-compatible object storage. The article contrasts this design with GitHub's earlier Spokes system, which used three-phase commit replication across local disks. Continuity uses stateless replicas that catch up from the log, and the article reports write throughput of up to 120 pushes/s on S3 Standard and over 300 pushes/s on S3 Express One Zone.

The article explains why hosting Git at scale is hard and how Continuity's WAL-based design compares with the earlier Spokes approach, which is useful background for infrastructure work.
