title: Netty based non-blocking REST framework
body: <p>I am working on a RESTfull application which requires high scalability. I am considering Netty based frameworks for RESTfull applications. I went through some of the available options and tried to get what they can offer as a non-blocking implementation. Here are my findings:</p>
  
  <ol>
  <li>rest.li --> Still under experimental phase for Netty based NIO implementaions. So, not production ready.</li>
  <li>RESTEasy --> Standard JBoss project which supports Netty 4.x. But,instead of full stack Netty based NIO implementation, RESTEasy is a Buffer exchange between Netty and RESTEasy. It's not taking the advantages of Netty. Therefore scalability is not as high as expected from a Netty based framework.</li>
  <li>Netty-http component --> Another  option is Apache Camel integration while using Netty-http component as an endpoint for routing requests to services exposed in from of beans. I think it's same as RESTEasy, only Netty-http component uses Netty based NIO capabilities and the rest of the system would use the old IO. I don't think I would help much in gaining scalabiltiy.</li>
  <li>RESTExpress --> It claims to be Netty based framework for RESTFull application. But, neither it has a decent community nor it can be trusted (Because it's very new) for enterprise application which requires high degree of security.</li>
  </ol>
  
  <p>Before having the above findings, I wanted to use some ready to use framework and get the work done faster. </p>
  
  <p>I know it's an opinion based question. But, still I seriously need help for choosing right framework for my application. If in case, there is no Netty based REST framework: would it be wise to go for plumbing low level Netty based NIO code in my application? Any help appreciated. Thanks in advance. </p>
