You can run Git on object storage if you re-make packfiles

AI Digest

文章提出通过重构Git packfiles格式，使Git能在对象存储上高效运行，解决了传统方式因网络延迟导致的性能瓶颈。

The article proposes a new packfile format for Git to run efficiently on object storage, overcoming performance issues caused by network latency.

Key points

• 传统Git packfiles为本地磁盘设计，对象存储需重新构建格式 Traditional Git packfiles are optimized for local storage, requiring reformatting for object storage
• 自定义列式存储格式提升对象存储访问效率 Custom columnar storage format improves object storage access efficiency
• 实际测试验证新格式可支撑生产级仓库性能 Production-scale repository tests validate the new format's performance
• 对象存储的网络延迟远超本地文件系统读取 Object storage network latency is orders of magnitude higher than local reads
• Git哈希计算与对象存储的异步特性存在兼容性挑战 Git's hash calculation conflicts with object storage's asynchronous nature

Takeaway: 重构packfiles格式是实现Git对象存储化的关键突破 / Reengineering packfiles is critical for Git's object storage implementation
