2021年,關恆開始思考前往美國的方法。當時,「走線」的方式仍未在中國人之間流行起來。他在研究資料之後,決定先到香港,然後飛往對中國免簽證的厄瓜多爾,再到巴哈馬,並在巴哈馬處購買了小型充氣船,在海上漂流近23小時後,偷渡進了美國的佛羅里達州。

But handling that stuff is slow. To calculate a string’s width it can’t call len on the string. Instead it has to pass every character through a state machine.

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.,这一点在谷歌浏览器【最新下载地址】中也有详细论述
