我在北京同仁医院的病床上度过了一段难挨的时光。那时,经过三期的化疗,身上的淋巴瘤已然全部消失,但药物的副作用也明显地显现出来:厌食、失去味觉、便秘、失眠。何况,后面还有四期、五期、六期、七期,最终可能要八期的化疗等着我。可想而知,我的心绪是何等沮丧。“掐着指头数日子”“天花板像一页读腻了的书”,这是臧克家先生住院时写下的诗句,如今的我,每天都不得不默诵几遍。

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.
