跨命名空间服务调用解决方案

支持功能

  • RPC支持两种调用方式：local+remote
  • 故障转移：根据策略，首先访问local，如果失败则访问remote
  • 失败探测：需要定义，哪些网络失败需要进行remote重试；或者通过哪些接口可以查询服务所处命名空间

讨论方案

路由自动探测方案

首先探测同一命名空间内的服务，如果失败，依次探测其他命名空间的服务（通过Proxy）。

强路由配置方案

通过配置文件，指定目标路由的命名空间。

缺陷
  • 配置运维
  • 无法灵活切换路由
  • 灾备/就近访问

就近访问+自动探测路由方案

优先探测访问同一命名空间的路由，如果失败，则访问proxy，proxy内部探测其他命名空间的路由。
