title: Is there way to commitSync() in Spring Kafka on Consumer side?
body: <p>In our use case we want to synchronously commit as soon as the message is proceed by the consumer. From looking at the <a href="http://docs.spring.io/spring-kafka/docs/1.0.0.M2/reference/htmlsingle/" rel="nofollow">http://docs.spring.io/spring-kafka/docs/1.0.0.M2/reference/htmlsingle/</a> I don't see a way to do this with current version of API. </p>
  
  <p>I do see there is <code>MANUAL_IMMEDIATE</code>, but still the underlying its <code>commitAsync()</code>. Is there a way of synchronously committing the transaction?</p>
