Subject Re: Message repetition consumption:Four consumers consume the same queue message, with two consumers receiving the same message at the same time, receiving a gap of 1ms
Date Mon, 11 Sep 2017 14:04:48 GMT
hi,
I confirm is two the same message, because their message id is the same, is not only the message
content is the same, there is no test of other ways to store, because my way is to use a zookeeper
+ leveldb deployment, when because of dirty data, leading to the master node and slave node
frequent switching, there will be a lot of this kind of duplicate messages, four consumers,
two or three, even four consumer receives the message with the same message id, and the receiving
time difference about 1 ms

Also, I'd want to know if the two messages had the same JMSMessageID (i.e. were they the same
message, or were they two different messages with the same content). On Sep 11, 2017 7:50
