There are times when it feels as though the entirety of British horse racing exists in a state of perma-gloom, bewailing an ageing fanbase, declining attendances and a moribund, factional leadership. It is, so the narrative goes, a sport in slow but irreversible decline, waiting for the inevitable moment in 10 or 20 years’ time when someone finally comes along to turn out the lights.
Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.
