Spanner is Google’s scalable, multi-version, globallydistributed, and synchronously-replicated database. It is the first system to distribute data at global scale and support externally-consistent distributed transactions. This paper describes how Spanner is structured, its feature set, the rationale underlying various design decisions, and a novel time API that exposes clock uncertainty. This API and its implementation are critical to supporting external consistency and a variety of powerful ...

Spanner is Google’s highly available global SQL database [CDE+12]. It manages replicated data at great scale, both in terms of size of data and volume of transactions. It assigns globally consistent real-time timestamps to every datum written to it, and clients can do globally consistent reads across the entire database without locking. This leads to three kinds of systems: CA, CP and AP, based on what letter you leave out. Note that you are not entitled to 2 of 3, and many systems have ...

谷歌的数据库Spanner 的论文 很全的论文！！！总共有三篇Google数据库的论文！我已经上传！

这是一个扳手模型。提供给各位下载使用。 This is a spanner 3D model.

CockroachDB 并没有尝试复制 Spanner 最不寻常的理念——用原子钟来让全球各地的数据中心时间同步。考虑到大多数线上应用都没有达到 Google 的规模，他们或许不需要这样的功能。真正需要的是是有一种稳定可靠的方式来让数据自动复制和同步到各个数据中心的服务器里，这样就算一个数据中心倒下了，应用还能正常运行，这也是 CockroachDB 的目标。
