title: Can single consumer read from multiple partitions of a kafka topic?
body: <p>There is a kafka topic with 16 partitions</p>
  <p>With a given consumer group name, we are currently launching single consumer to read from the topic.</p>
  <hr />
  <ol>
  <li><p>Does single consumer read from <code>partition 0</code>(only) of that topic?
  If <code>partition 0</code> has gone empty with messages, does consumer start reading from next partition(<code>partiton 1</code>... and so on)?</p>
  </li>
  <li><p>we have option to launch more than consumer(with same consumer group name) to read from same topic(having 16 partitions). How many consumers can be maintained, to read from multiple partitions parallely?</p>
  </li>
  </ol>
