UPDATE: This presentation is out-of-date. We changed a lot of things in the public API since then.
Netty is a Java asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. It powers many large scale services built on top of JVM such as Twitter.
This talk will provide an overview of Netty 4, the major backward-incompatible update against the version 3, from basic constructs to a working example. It's not necessarily for those who are familiar with the previous versions on Netty.
