是否有具有可定制复制级别的多主数据库？ [英] Is there multi master database with customizable replication level?

问题描述

我需要一个多主数据库，让用户从不同的大陆说话。每个用户将他的数据写入他的本地主数据库，它将数据复制到其他县/大陆的其他主数据库。
问题是我无法在所有数据中心存储所有用户数据的所有副本。我需要一个像数据库/解决方案，这将允许我设置一个复制级别。

我需要有能力从任何节点读取任何数据，但在几个节点上存储数据（在3个节点上，但不是在所有节点）。


是否有解决方案？也许在数据库和应用程序或聪明的集群之间的代理？任何想法或提示都会令人愉快。

I need a multi master database to let users talk from different continents. Each user will write his data to his local master database and it will replicate data to other master databases in other counties/continents. The problem is that I can't store all copies of all users data in all data centers. I need something like a database/solution which will let me to set a replication level.
I need to have ability read any data from any nodes but store data on several nodes (on 3 nodes but not on all nodes).

Is there the solution? Maybe a proxy between database and application or a clever cluster? Any ideas or tips will be pleasant

推荐答案

您可以使用分布式缓存来实现此结果。查看他们如何在WAN复制策略下工作。

You could use a distributed cache to achieve this result. Check out how they work under WAN replication strategies.

例如，查看 NCache Wan复制（桥）

PS：分布式缓存将所有数据保存在内存中，你也可以坚持下去。

PS: A distributed cache keeps all of the data in memory for performance reasons. You could persist it as well.
