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.,推荐阅读雷电模拟器官方版本下载获取更多信息

下游的优势在于市场想象空间巨大,估值弹性高,一旦实现技术突破,有望获得垄断性收益。但风险远高于上下游:盈利周期极长,预计要到2030年才能实现现金流转正;技术路线失败率高,类似Meta元宇宙投入效果不佳的案例并不少见;且资本依赖性极强,一旦融资环境恶化,将直接冲击企业生存。
