hi,对这个功能我有点疑问,是否细粒度到topic级别,到broker级别应该就足够了吧。控制broker是否可发送,可订阅。

存在这样的场景,转移topic,比如一个量大的topic需要重差机器上面上面转移到好机器上面,但不能丢消息,只能停在发送,直到消息消费完成,然后在从这个差机器中删除topic相关信息

这样的场景目前就可以实现了,无需停止发送,只要暂停该broker,将该topic的数据全部拷贝到新机器上即可。因为你的服务是集群,暂停一台broker做拷贝是毫无关系的。当新机器起来的时候,消费者会去新机器继续消费。

:),我们broker没有用master slave方式,而且不能停止broker . 其实我们是b2b的,我们这边napoli是一个推拉结合的,不分开的,拉的服务器就是用你的优秀的metaq

不是有个关闭分区功能吗,把这个topic的全部分区关闭掉是否满足需求?

已提交一个功能实现,添加参数acceptPublish和acceptSubscribe来控制broker和topic是否允许接收消息或者接收订阅。
这两个参数同时是system参数,也可以被topic的配置覆盖。
