title: changelog topic in Kafka streams - setting or altering partitions
body: <p>We have a stream processor app that consumes the data from a topic with n partitions ( n &gt; 1 ).<br><br>
  From the fresh start (without the changelog topic), the dev environment always creates a changelog topic with n partitions.</p>
  <p>In the same scenario,  on production the number of partitions is always equal to 1 then we have manually changed to n to match the # of partitions of the topic.</p>
  <p>I check all the documents try to set the number of partitions for the changelog but I could not find any way to do it. My last option is to check if the changelog topic does not exist then I create it with n partitions.</p>
  <p>Since the framework creates that topic automatically, are there any way to set the number of partitions for the changelog without creating that topic manually or in code?</p>
  <p>PS: We are using Kafka client version 2.3.1.</p>
  <p>Thanks,</p>
