                为什么Google上十亿行代码都放在同一个仓库里?

导读：相对于一般公司，Google 使用了单一代码仓库，很多人不理解为什么这么做。本文作者是谷歌基础设施小组的工程师，对这个问题进行了详细解读。译者在翻译过程中受益良多，也相信大家看完之后会认为自己还活在史前时代。
早期 Google 员工决定使用集中式源代码管理系统来管理代码库。 这种方法已经在 Google 运行了 16 年以上，而今天绝大多数的 Google 软件仍然存储在一个共享的代码库中，随着 Google 开发软件数量稳步增加，Google 代码库的规模也呈指数增长（图1）。 因此，用于管理代码库的技术也发生了显著变化。
