Usually every time a trouble in your project, as follows:
Application has A, B,
Application sends A message, A topic: A, B application to subscribe to the topic: A, the tag: tag1, consumer groups are: group1
At this point, if there is A need to have A project, A need to send the tag: tag2, so in the project environment, I B application subscription tag1 and tag2, then due to the same topic as group, lead to public environment also subscribed to tag2 (RocketMq topic + group as the only sign, subscribe to the relationship between the only below), so at this time, I deal with is in the test, send A message to add A prefix - & gt; Prefix_tag2 and consumption group to prefix_group B, so this time will not affect the,
The simple case for example, there are only two applications, more facts of the company's application, the process is more complex, message interaction is more, involving the application of a lot, so if you want to add a tag message, change the application of prefix is a lot of, each time there is a message change, all need to change a lot of applications to build such a message environment, very trouble, don't know how to deal with the problem of other companies is, so I ask you, is there any good way to solve such a problem
