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.,详情可参考WPS下载最新地址

We’d recommend the Fire TV Stick 4K Plus overall, but if you just want a cheap and basic 4K streaming stick — maybe one for a second or third TV — the standard Fire TV Stick 4K is hard to ignore at $20. The redesigned Fire TV OS has yet to roll out to the stick, and it has half the RAM so it’s slower. It also lacks Dolby Vision and Dolby Atmos support, but it still supports HDR10, HDR10 Plus, and Alexa Plus while including an Alexa Voice Remote. You also get access to all the major streaming services, while Xbox Game Pass Ultimate subscribers can stream select games from the cloud as they can on Amazon’s other sticks.
