What are the four main IO models in Java?
The four main IO models in Java are blocking I/O model, non-blocking I/O model, multiplexed I/O model and asynchronous I/O model. This topic provides you with articles, downloads, and course content related to io models for everyone to download and experience for free.
What are the four main IO models in Java?The four main IO models in Java are blocking I/O model, non-blocking I/O model, multiplexed I/O model and asynchronous I/O model. Detailed introduction: 1. The blocking I/O model is one of the most basic I/O models. Its characteristic is that the current thread will be blocked when performing an I/O operation, and subsequent code will not continue to be executed until the I/O operation is completed. In the blocking I/O model, when a thread calls a read operation, if there is no data to read, the thread will block on the read operation until data arrives, when a thread calls a write operation, and so on.
This article will take you to quickly understand the thread IO model in RedisRedis is single-threaded, but why is it so fast? One reason is that redis uses non-blocking IO and multiplexing to handle a large number of client connections. The following article will take you to understand the thread IO model in Redis. I hope it will be helpful to you!
Overview of Java IO model and Netty frameworkWhat is Netty asynchronous? It is an event-driven network application framework that is used to quickly develop high-performance, highly reliable network IO programs. It is mainly aimed at high-concurrency applications for Clients under the TCP protocol. It is essentially a NIO framework, suitable for server communication, etc. Scenario asynchronous: sending a request without waiting for a response, the program continues on. Event-driven: a connection event or disconnection event, or a read event or a write event, and subsequent processing after the event occurs. Typical applications of Netty: high-performance rpc framework is used for remote service (process) calls, such as Dubbo. Game industry, page data interaction. Big data areas such as Hadoop high-performance communication and serialization components (AVRO). A simple understanding of the IO model is to use what pass
