2月26日,携程集团公布了其2025年业绩公告。去年全年,该集团实现净收入624亿元,剔除投资收益的净利润为134亿。当市场习惯性地从营收、净利润等数字中探寻增长与衰退的线性轨迹时,这份报告却揭示了一个更为深刻的趋势:在流量红利见顶、行业竞争格局趋于固化的当下,头部平台正经历一场静水流深的角色蜕变。

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.
