title: What is the difference between "seda + concurrentConsumers" and "direct + threads"
body: <p>Apache Camel provide two solutions for using thread pool:</p>
  
  <p><code>from("seda:stageName?concurrentConsumers=5").process(...)</code></p>
  
  <p>and </p>
  
  <p><code>from("direct:stageName").thread(5).process(...)</code></p>
  
  <p>I would like to know, what is the difference between the two solutions ? Is it just two kind of write the same thing or not ? What are the use cases ?</p>
