作用
NameServer作為rocketmq中重要的組件其主要有如下功能：
在官網(wǎng)概念介紹如下 https://rocketmq.incubator.apache.org/docs/core-concept/
Name server serves as the routing information provider. Producer/Consumer clients look up topics to find the corresponding broker list.
也就是說
- 每個(gè)broker啟動(dòng)的時(shí)候會(huì)向namesrv注冊(cè)
- Producer發(fā)送消息的時(shí)候根據(jù)topic獲取路由到broker的信息
- Consumer根據(jù)topic到namesrv獲取topic的路由到broker的信息
