title: Can different nodes of same service act as consumer and producer?
body: <p>I have deployed my service on three different node.</p>
  <p>I have a scenario where a user does some update (eg add new menu) which will go to nosql db(mongo).</p>
  <p>I want to use Kafka so that one node will produce the event(new items added to menu) and all other node will consume .</p>
  <p>The difficulty which I have is all nodes are running same service.</p>
  <p>How can one act as a producer and others as consumer in Kafka?</p>
