你能推荐一个水平缩放的数据库吗？ [英] Can you recommend a database that scales horizontally?

问题描述

通常，数据库服务器是最大，最昂贵的盒子，我们必须购买，因为垂直缩放是唯一的选择。是否有任何可以横向扩展（即跨多个商品机器）的数据库，以及这种方法有什么限制？

Generally the database server is the biggest, most expensive box we have to buy as scaling vertically is the only option. Are there any databases that scale well horizontally (i.e. across multiple commodity machines) and what are the limitations in this approach?

推荐答案

Don不用担心，好的解决方案即将到来！

Don't worry, good solutions are coming!

Couchdb 和 Hypertable 都是开源的，但仍然是alpha的，但它们明显是为了缩放商品软件简单。

Couchdb and Hypertable are open source and still in alpha, but they are clearly designed to make scaling on commodity software simple. They work pretty well, and may change how you think about databases.

此外，如果可以让其他人为您分发， Google AppEngine 和 Amazon SimpleDB 是非常便宜的分布式数据库服务，虽然他们现在都处于测试阶段，因此施加严格的限制。

Also, if it's okay to let someone else do the distributing for you, Google AppEngine and Amazon SimpleDB are extremely cheap distributed database services, though they're both in beta right now so strict limitations are imposed.
