RocketMQ部署及使用-Go

前言

rocketmq目前已经支持了5.0版本,近段时间看了一下官方文档和clientGo客户端，发现5.0和4.X区别还挺大的。抱着learning is endless态度,那就开学吧。

RocketMQ部署

创建主题

mqadmin 创建

在rocketmq v5版本下，producer在发送消息前需创建主题。

rocketmq@654f1dd329a4:~/rocketmq-5.3.1/bin$ sh mqadmin updateTopic -n rmqnamesrv:9876 -b rmqbroker:10911 -t normal-topic -a +message.type=NORMAL

自动创建

在rocketmq v4版本下，主题可以在produce message时进行创建
