Inside Cloud Spanner and the CAP Theorem | Google Cloud Blog
Building systems that manage globally distributed data, provide data consistency and are also highly available is really hard. The beauty of the cloud is that someone else can build that for you. The CAP theorem says that a database can only have two of the three following desirable properties: C: consistency, which implies a single value for shared data A: 100% availability, for both reads and up
Cloud Spanner: A global database service for mission-critical applications | Google Cloud Blog
Introducing Cloud Spanner: A global database service for mission-critical applications Today, we’re excited to announce the public beta for Cloud Spanner, a globally distributed relational database service that lets customers have their cake and eat it too: ACID transactions and SQL semantics, without giving up horizontal scaling and high availability. When building cloud applications, database ad
Exclusive: Inside Google Spanner, the Largest Single Database on Earth
Much like the engineering team that created it, Google Spanner is something that stretches across the globe while behaving as if it's all in one place. Unveiled this fall after years of hints and rumors, it's the first worldwide database worthy of the name -- a database designed to seamlessly operate across hundreds of data centers and millions of machines and trillions of rows of information. Eac
Spannerお勉強メモ - スティルハウスの書庫の書庫
Spannerお勉強メモです。かなり久々の技術系エントリだ。。 朝起きてTwitterみてたら@ichiro_satoh先生のこんなつぶやきが。 現時点ではGoogle Spannerの一番詳しい資料かも。berlinbuzzwords.de/sites/berlinbu…— ICHIRO SATOHさん (@ichiro_satoh) 6月 6, 2012 。。やっぱりGoogleのインフラ情報は学会発表で流れてくるケースが多いなぁと思いつつ、先日公開されたF1（Google規模でスケールするRDB。AdWords用に使われてる）でもSpannerが重要なカギを握っているので、ついカッとなってスライドの要点を訳してみました。 原文はこれです：Building Spanner - Better clocks → stronger semantics（セッションのビデオ） 一行に要約すると、
Spanner: Google's Globally-Distributed Database
Spanner is Google's scalable, multi-version, globally-distributed, 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 AP
