title: How to get data from old offset point in Kafka?
body: <p>I am using zookeeper to get data from kafka. And here I always get data from last offset point. Is there any way to specify the time of offset to get old data?</p>
  
  <p>There is one option autooffset.reset. It accepts smallest or largest. Can someone please explain what is smallest and largest. Can autooffset.reset helps in getting data from old offset point instead of latest offset point?</p>
