Netty's threading model Reactor model Netty's model is based on Reactor mode, so we must know Reactor first. The Reactor model is also called the Dispatch model. When one or more requests are sent to the server at the same time, the server synchronously assigns them to the processing threads of each request. Three roles of Reactor model Ac ...

brief introduction When we introduced channel, we mentioned that almost all the implementations in channel are implemented through channelPipeline. As a pipeline, how does it work? Let's have a look. ChannelPipeline ChannelPipeline is an interface, which inherits three interfaces: channelinboundinvoker, channeloutbooundinvoker and Itera ...

Traditional blocking schemes usually use other threads to process when there are new links, and each thread is responsible for processing a socket, such as ServerSocket serverSocket = new ServerSocket(3000); while(true){ Socket socket = serverSocket.accept(); new Thread(()->{ ...

This series of Netty source code analysis articles is based on 4.1.56 Final version In this paper, the author will introduce the operation architecture of Netty's core engine Reactor. I hope that through this introduction, we can have a comprehensive understanding of how Reactor drives the operation of the whole Netty framework. It also pa ...

In the previous chapter, we analyzed the creation and initialization of NioServerSocketChaennl in Netty. In this chapter, we will continue to analyze the analysis of NioServerSocketChannel. NioServerSocketChannel is a channel object officially encapsulated by Netty, which is intended to replace or package the native SocketChannel object of JDK, ...

preface The last chapter introduces the development process and practical application of Io. When talking about the multithreading model of multiplexer, I have gone through it. This chapter will supplement here, and then go to Netty's IO model. Finally, the idea will be realized through code. 1, Introduce In the previous chapter, a multiplex ...

BIO, NIO and AIO are not suitable for students with poor foundation. They need to be proficient in Java OOP programming, have certain programming thinking, be familiar with Java multithreading programming, Java IO stream programming, Java network programming, and be familiar with common Java design patterns Most of the people in BIO have b ...

1, Introduction 1, Overview Netty is an open source framework provided by JBOSS. In essence, it is a network application framework. It provides a non blocking and event driven network application framework and tools to facilitate the rapid development of high-performance and reliable network server and client. 2, Core architecture         ...

1. Inheritance system diagram of nioeventloopgroup You can see that the EventExecutorGroup inherits from ScheduleExecutorService and Iterable This means that there are thread pools and iterators. What does NioEventLoopGroup do to the thread pool and what are iterators iterating? Look down~ 2. Function description of eventexecutorgroup c ...
