title: How to use JDBC to maximize performance of Netty?
body: <p>I am developing a HTTP application server using Netty 4 and JDBC(+BoneCP for connection pooling).</p>
  
  <p>So far, I am doing all the work(works involving database connections, HttpAsyncClient and so on) on one handler. I close all I/O after each job is finished. </p>
  
  <p>As far as I know, Netty performs well as long as nothing is blocking the worker thread.</p>
  
  <p>However, I <a href="https://stackoverflow.com/questions/4087696/is-asynchronous-jdbc-call-possible">read</a> that JDBC connections create blocking I/O. </p>
  
  <p>Is there a good practice to use JDBC with Netty to improve scalability and performance?</p>
