Netty 4 Overview // Speaker Deck
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 necessaril
Netty 4 at Twitter: Reduced GC Overhead
At Twitter, Netty (@netty_project) is used in core places requiring networking functionality. For example: Finagle is our protocol agnostic RPC system whose transport layer is built on top of Netty, and it is used to implement most services internally like Search TFE (Twitter Front End) is our proprietary spoon-feeding reverse proxy which serves most of public-facing HTTP and SPDY traffic using Ne
オリジナルの通信プロトコルを実装してみよう(Netty 実践編2) - Taste of Tech Topics
こんにちは！新しい物好きなエンジニアのツカノです。 Nettyを利用しているOSSは多いですが、Netty4が登場して気になるのはNetty3からの移行ですよね。どのくらいのプロジェクトが移行しようとしているかは分かりませんが、Issueを見ているとNetty4への移行話が登場しているものもチラホラあります。個人的には移行状況もチェックしておきたいと考えています。 さて、前回の実践編1では、オリジナルプロトコルのEncoder/Decoderを作成しました。今回の実践編2ではEncoder/Decoder以外の部分(クライアント/サーバのプログラム)を作成し、ChannelBufferについて解説します。 クライアントのプログラム 以前のシリーズで紹介したクライアントプログラムを参考に、書いてみましょう。 MyProtocolClient StringEncoder/Decoderだった部

Netty MJPEG streamer
Some time ago, I needed to view a Java Swing window online through a browser. I could’ve looked into something like the awesome GTK Broadway backend, but I needed something which was a bit easier to setup (and I didn’t want to install all kinds of X libraries on my server). Then I remembered those online live webcam feeds, they work by just streaming JPEG images to the browser continuously (see MJ

Netty: Netty 3.3.1 released - SPDY Protocol !
The Netty project team is proud to announce Netty 3.3.1. The JAR file is already on Maven central repository. You can also get the full tarball from the download page. This version introduces a couple exciting features. The most important one is the new SPDY package, which was contributed by Twitter. If you develop for Android, you will be happy to hear that this release fix the incompability with
Finagle, from Twitter
Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers. Finagle implements uniform client and server APIs for several protocols, and is designed for high performance and concurrency. Most of Finagle’s code is protocol agnostic, simplifying the implementation of new protocols. Finagle is written in Scala, but provides both Scala and Java idiomatic APIs. GitHub p
