title: Keep order in Kafka after reproducing messages by using Storm
body: <p>I use Apache Kafka as my Storm spout.
  I receive the messages from Kafka, process these messages and them send them back to the Kafka.</p>
  
  <p>I wonder if I can keep the messages in same sequence. i.e.</p>
  
  <p>topic01: A, B, C -> Storm -> topic02: A_, B_, C_</p>
  
  <p>I used one spout and one bolt to try to keep the order, but it won't work.
  I tried OpaqueTridentKafkaSpout too, but the order still changed.</p>
  
  <p>So are there any solutions to solve this problem?
  Thank you.</p>
