在GAE中，什么是高复制数据存储？ [英] In GAE, What is high replication datastore?

问题描述

我是GAE中的一名新手，我想介入几乎所有事情，所以这是下一步。 解决方案

您可以查看： http：//googleappengine.blogspot .com / 2011/01 / announcing-high-replication-datastore.html

高复制数据存储提供最高级别的读取和写入的
可用性，代价是写入的延迟
延迟以及API中一致性保证的更改。
高复制数据存储通过使用Paxos算法来
实时同步跨数据中心的数据，从而增加了维护数据副本的数据中心数量
。
最重要的好处之一是，您的应用程序
的所有功能将在计划维护期间保持完全可用，如
以及大多数计划外基础架构问题。

希望这有助于您。

I am a newby in GAE and I want to get involved on almost everything, so this is the next step.

解决方案

You can have a look at: http://googleappengine.blogspot.com/2011/01/announcing-high-replication-datastore.html

The High Replication Datastore provides the highest level of availability for your reads and writes, at the cost of increased latency for writes and changes in consistency guarantees in the API. The High Replication Datastore increases the number of data centers that maintain replicas of your data by using the Paxos algorithm to synchronize that data across datacenters in real time. One of the most significant benefits is that all functionality of your application will remain fully available during planned maintenance periods, as well as during most unplanned infrastructure issues.

Hope this helps.
