title: Can single Kafka producer produce messages to multiple topics and how?
body: <p>I am just exploring <code>Kafka</code>, currently i am using One <code>producer</code> and One topic to produce messages and it is consumed by one <code>Consumer</code>. very simple.</p>
  
  <p>I was reading the Kafka page, the <code>new Producer API is thread-safe</code> and sharing single instance will improve the performance.</p>
  
  <p>Does it mean i can use single Producer to publish messages to multiple topics?</p>
