title: Selecting executors in Jenkins?
body: <p>In my company we're using a single Jenkins build server. We have resource-heavy interdependent build jobs as well as smaller ones, equally important. During peak times, the big builds tend to block the pipeline. </p>
  
  <p>My question: is it somehow possible to select a single executor (not a node) and assign certain jobs to it so it will always be free for the lightweight ones?</p>
  
  <p>I <em>know</em> I could set up slave nodes, even on the same machine, and that it's very common and much supported by Jenkins. Our server could handle a vm running as a slave, but before I go to the trouble I want to know if there's a shorter way. </p>
  
  <p>Cheers</p>
