Navi is a distributed service framework that provides cluster management and high performance RPC. With Navi, you can easily build distributed applications with minimal effort to create a highly scalable architecture capable of handling remote procedure call and service registration and discovery.
Implemented in Java and Spring framework, Navi wraps ZooKeeper and uses Protostuff/Protobuf for transport to make it easy to build a cluster aware application. Navi allows you to focus your efforts on your application logic, so programming experience is very friendly with its simple XML or annotation configuration.
Navi全称可理解为navigation，即“制导/导航”的意思。
Navi是一个分布式服务框架，提供高性能和无侵入式的RPC远程服务调用方案，以及部分服务治理方案，秉承简单够用、灵活扩展的开发原则。
利用Java以及Spring Framework实现，集成Zookeeper，使用HTTP原生通信模型，利用Protostuff/Protobuf作为序列化协议。同时提供了灵活的配置方式，XML或者注解方式使开发一个服务变得非常容易。
- Providing high availability. By using zookeeper for the underlying group management, Navi can make it easy to publish/remove service nodes.
- Providing Protostuff/Protobuf to serialize and deserialize data.
- Using optional software load balancing and failover strategy.
- Simple configuration with XML or annotation way to expose services in Spring.
透明化的远程方法调用，就像调用本地方法一样调用远程方法，只需简单配置，没有任何API侵入。提供基于长连接的、池化HTTP的通讯基础，提供“请求-应答”模式的信息交换。
高性能、多序列化协议支持，以及软负载均衡，失败容错，地址路由等集群支持。
基于注册中心目录服务，使服务消费方能动态的查找服务提供方，使地址透明，集群整体保证高可用性。服务发布简单自由，使服务提供方可以平滑增加机器，做到横向水平扩展。
