introduction

• An inter-container messaging mechanism that does not require a TCPIP network. The underlying protocol is Unix DomainSocket, The non-blocking threading model relies on the Netty Event Loop, The message plan has a simple structure that is customized. Fast and efficient analysis, Meet the needs of KV storage, direct forwarding and other features.

• Implementation brief: Unsafe access native Epoll ctl as the primary non-blocking support, Epoll’s EPOLLIN,EPOLLOUT,EPOLLRDHUP,EPOLLET,EPOLLERR is supported

• Message specification

  1-2	3-6	7-bodylen
  type num(u16)	body len (u32)	bytes

• KV storage support:

  Extend Java memory through mmap to improve access efficiency. Supports per-block compression to reduce storage pressure. Support setting cache to optimize IO pressure.

介绍

• 一种无需TCPIP网络的容器间的消息传递机制。 基础protocol是Unix DomainSocket， 非阻塞线程模型依赖Netty Event Loop， 消息规划采用自定义的简单结构， 解析迅速，高效， 满足kv存储，直接转发等多种feature。

• 实现简介： 采用Unsafe 接入native Epoll ctl 作为主要的非阻塞支持， 支持了Epoll的EPOLLIN,EPOLLOUT,EPOLLRDHUP,EPOLLET,EPOLLERR

• 消息规范

  1-2	3-6	7-bodylen
  type num(u16)	body len (u32)	bytes

• kv存储支持:

  通过mmap扩展java外存，提高存取效率。 支持按块压缩，降低存储压力。 支持设置缓存，优化io压力。
