hi, 1. you should check, if your topic partition really have one. 2. does your consumer get same message or different message. e.x all message is 1,2,3,4,5,6,7. consumer1 get 1,3,7 consumer2 get 2,6, consumer3 get 4,5?

There are also 3 consumers consuming from that topic. Now all the docs I have seen say that if number of consumers is bigger than the number of partition ( like in my case 3 consumers 1 partition), then only one consumer will get messages and the other two will not get any, nonetheless, they are all connected. However, in my case, all the three consumers are getting messages. Any ideas why this is happening?
