title: Kafka streams - disable reading state from changelog
body: <p>I've created an application using Kafka Streams, and doing some aggregations over my input topic.</p>
  
  <p>Right now, when the application starts up it takes a few minutes for it to reproduce its state from kafka changelog (state dir is not persistent between start ups).</p>
  
  <p>I would like to disable reading from changelog in startup, meaning it will start from scratch. Is it possible?</p>
