title: Are kafka acks received in the same order of produced messages
body: <p>I'm working on a process that collect data from IBM MQ and process it to a kafka topic.
  To make sure not loosing any message,I need to commit my JMS message only after making sure my message is being sent and received by kafka broker.
  I don't want to use synchronous kafka producer (waiting on future.get()) because of the performance impact it may have,instead I want to commit my JMS message inside the callback I'm providing my kafka producer.
  For this to work correctly, I need the garantee that ack will be received in the same order of my produced messages (first ack corresponds to the first message being sent..).</p>
  <p>Is my assumption correct?</p>
