1. Group RocketMq one consumer group, every consumer to subscribe to the same topic and the tag (group, that is to say, the topic, the tag three parameters are exactly the same)
"2. "within the same consumer groups, set different tag, when after the start of consumers will cover first start consumers set the tag"
Question 1: the same service, the deployment of multiple clusters, in which each individual cluster deployment node have relations between the two kinds of subscription
A. groupName, topic, the tag
B. groupName, topic, tag1
According to the statement, the club's official website at program startup. A, b consumers to subscribe to overwrite the tag, then a and b in one of which is a failure, so what should I do?
Question 2: when I simulate the situation of problem 1 found that even a, b, one of the effective, also only is only part of the message is received?
CodePudding user response:
Website has said very clearly, if you start a first, then only consumption tag, and then you start b, then a, b are only consumption tag1, the rest of the tag will consume not arrived,
