Cursor outlines a WAL-first approach to Git hosting at scale

In this Cursor engineering post, Vicent Martí explains why Git’s packfile format and consistency requirements make repository hosting difficult at scale. He contrasts prior filesystem, object-store, and Spokes-style replication approaches with Continuity, Cursor’s WAL-first design that keeps S3-compatible object storage as the source of truth while treating local Git repositories as caches. The post matters because it frames how AI-driven growth in repositories and CI workloads could pressure version-control infrastructure, though its product and performance claims are Cursor’s own.
