Abstract: Techniques are provided to allow users to define a global service that is offered across multiple replicated databases. Database clients connect to and use a global service just as they do with regular services on a single database today. Upon receiving a connection request, a collection of components, referred to collectively as the Global Data Service framework (GDS framework), automatically chooses the best database server instances to which to connect a client. Once those connections have been established, the clients determine which database server instance, of those database server instances to which they are connected, to send requests to based, at least in part, on advisory messages sent to the clients by the GDS framework.

Abstract translation: 提供技术以允许用户定义跨多个复制数据库提供的全局服务。 数据库客户端连接到并使用全局服务，就像现在一个数据库上的常规服务一样。 一旦接收到连接请求，将统称为全局数据服务框架（GDS框架）的组件集合自动选择连接客户端的最佳数据库服务器实例。 一旦建立了这些连接，客户端将确定哪些数据库服务器实例（与其连接的数据库服务器实例）发送请求至少部分地基于由GDS框架发送给客户端的咨询消息。
