What is the difference between Vert.x and Netty? Why should one ever prefer Netty over Vert.x?
Both of them are event-driven, non-blocking and asynchronous frameworks designed for high-load I/O.
Vert.x is based on Multi-Reactor pattern (Node's style event loop on multithreaded JVM) but Netty use Interceptor Chain Pattern. When Interceptor Chain Pattern has any benefits over Multi-Reactor pattern ?
I just have a quick look at Netty's documentation, but it seems Vert.x has some extra funcitonality over Netty. I.e. Vertx is a standalone server, it's a polyglot, provide HA and clustering out-of-the-box.
Also Vert.x has little bit better benchmarks than Netty.
P.S. Disclaimer - I appreciate Vert.x very much, and not familiar with Netty. So by asking Why should one ever prefer Netty over Vert.x? I just trying to compare both of them.
