title: Spring cloud stream kafka binding configuration max request
body: <p>I am using spring cloud stream kafka.</p>
  
  <p>I am trying to send data to kafka which is more than the default 1000KB.</p>
  
  <p>I set <code>message.max.bytes</code> in server.properties file as given below:</p>
  
  <pre><code>message.max.bytes=20000000
  </code></pre>
  
  <p>and application.properties in my springboot app looks like:</p>
  
  <pre><code>spring.cloud.stream.kafka.bindings.&lt;channelName&gt;.producer.configuration.max.request.size=20000000
  </code></pre>
  
  <p>This works. 
  However, I would like to generalize all topics in spring cloud kafka to be able to send large files to the channelName. How can I set the properties so that I am able to send large file (above 1000KB) to all channels? Thanks</p>
