title: Does gRPC server spin up a new thread for each request?
body: <p>I tried profiling a gRPC java server.  And i see the below set of thread pools majorly.</p>
  
  <ul>
  <li>grpc-default-executor Threads : Created 1 for each incoming request.</li>
  <li>grpc-default-worker-ELG Threads: May be to listen on the incoming gRPC requests &amp; assign to the above "grpc-default-executor" thread.</li>
  </ul>
  
  <p>Overall, is gRPC java server, Netty style or Jetty/Tomcat style?  Or it can configured to run as both ways?</p>
