基于通用消息的持久化消息队列设计

DESIGN OF PERSISTENCE MESSAGE QUEUES BASED ON COPART-MACO

一个成熟的分布式中间件应提供不同进程间寻址和通信能力,同时提供高可靠的通信服务质量.有些中间件可提供很好的消息寻址和通信的能力,但不能保证通信可靠性.通用消息就是这样的一种中间件,为了改进它的服务质量,本文充分利用了其寻址和通信优势,引入队列和持久化思想,设计了一种消息持久化队列Ebupt Message Queue(EMQ).在实际应用中,EMQ可为上层提供更加可靠的通信服务质量.EMQ支持持久化,也可以满足非实时性消息通信的场景.

A mature distributed system middleware should provide addressing, communication between different processes and guarantee the quality of service simultaneously. Some middlewares provide good addressing and communication abilities, but lack of quality of service. COPART-MACO is such a middleware. To improve its quality of service, the paper took advantage of its addressing and communication abilities, inducted message queue and persistence, designed Ebupt Message Queue （EMQ）. In practice, EMQ can guarantee the quality of service for upper layer application. Moreover, EMQ provided persistence, which made it meet the demand of some non-reahime message communication scene.
