title: Kafka having duplicate messages
body: <p>I don't see any failure while producing or consuming the data however there are bunch of duplicate messages in production. For a small topic which gets around 100k messages, there are ~4k duplicates though like I said there is no failure and on top of that there is no retry logic implemented or config value is set.</p>
  
  <p>I also check offset values for those duplicate messages and each has distinct values which tells me that the issue is in producer.</p>
  
  <p>Any help would be highly appreciated</p>
