rqlite是一个轻量级的分布式关系数据库，它使用作为其存储引擎。 形成集群非常简单，可以很好地处理领导者选举，并容忍包括领导者在内的机器故障。 rqlite可用于Linux，macOS和Microsoft Windows。
查看。
为什么？
rqlite为您提供，容错的，复制的关系数据库的功能，但安装，部署和操作非常简单。 有了它，您将获得轻量级且可靠的分布式关系数据存储。 考虑一下或 ，但也可以使用关系数据建模。
您可以将rqlite用作大型系统的一部分，作为一些关键关系数据的中央存储，而不必运行更大，更复杂的分布式数据库。
最后，如果您想了解分布式系统的实际工作方式，那么rqlite是一个很好的例子。 在其和实现中已经进行了很多思考，各个组件之间的清晰分离，包括存储，分布式共识和API。
怎么样？
rqlite使用在SQLite数据库的所有实例之间达成共识，从而确保对系统所做的每个更改都是针对一定数量SQLite数据库进行的，或者根本不进行。 您可以在了解有关该设计的更多信息。
主要特点
易于部署，无需单独安装SQLite。
完全复制的生产级SQL数据库。

用于HTTP Ruby API
常问问题
外交官干什么？
Diplomat允许任何ruby应用程序与分布式键值存储进行交互，并且还可以接收有关Consul群集中当前可用服务的信息。
它可以在轨道上工作吗？
对！ 实际上，我们在所有的Rails生产应用程序中都使用了它，而不是以前的任何情况（根据正确使用环境变量）。 这使我们能够在不更改实际项目代码库的情况下进行扩展，并轻松地在集群中移动应用程序。
这是生产数据库.yml文件的外观：
