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.

但广告化并不天然等于价值创造。当所有商户都必须通过竞价才能被看到时,广告费便从增量工具演化为入场券。单个商户的理性选择,是继续加价以维持原有订单量;但从整体看,供给侧为此付出的总成本却在不断上升,而需求并未同步扩大。平台收入提高,但供给侧整体并未获得更多有效需求,反而陷入内耗式竞价。这种结构下,广告化更像是将抽佣换了一种更隐蔽的形态,甚至加剧了零和博弈。
