摘要

Spanner是Google的可扩展、多版本、全球分布式和同步复制数据库。它是第一个在全球范围内分发数据并支持外部一致的分布式事务的系统。本文描述了Spanner的结构、它的特性集、各种设计决策的基本原理,以及一个暴露时钟不确定性的新型时间API。该API及其实现对于支持外部一致性和各种强大功能至关重要:过去的非阻塞读取、无锁快照事务和跨所有Spanner的原子模式更改。

Spanner
Spanner is Google’s scalable, multiversion, globally distributed, and synchronously replicated database. It is the first system to distribute data at global scale and support externally-consistent distributed transactions. This article 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 features: nonblocking reads in the past, lock-free snapshot transactions, and atomic schema changes, across all of Spanner.
