Haafiz is a gateway in Micro Service which is inspired by many open source gateway :Zuul 1.x , spring cloud gateway，currently not released now ......

Haafiz （在英文中是守护者的意思）参考了很多开源网关的思想，基于Netty，Disruptor，etcd等技术做一个开源网关目前，目前还未发布正式版本

Design HighLights

• asynchronized request &response
• Disruptor& MPMC（multi producer and multi consumer）to support higher performance
• Netty Reactor
• load balance design refernce from Dubbo
• Make full use of cache (config&route rule&ReferenceConfig in dubbo&loadbalance strategy...)
• FilterChain design reference to Netty &Sentinal
• serialization for quick response data & parallelization for heavy time-consuming data
• OpenTracing protocol and RollingNumber to track request& response

设计亮点

• 异步请求响应
• Disruptor &MPMC高性能实现
• Netty Reactor线程模型
• 参考Dubbo的负载均衡设计
• 充分使用缓存（配置，路由规则，负载均衡策略）
• 参考 Sentinel和Netty的FilterChain 职责链模型设计
• 串行化和并行化优化
• 基于Opentracing和RollingNumber的请求，响应记录
