I. IO model Introduction
To better understand the IO model, we need to review in advance: synchronous, asynchronous, blocking, non-blocking

Preface
Socket. io provides real-time event-based two-way communication. This article introduces socket. io in depth. Let's take a look at the details below.

By default, socket. io uses the socket. io-client package to provide socket
The traditional IOStream-oriented input and output systems such as InputStream, OutputStream, Reader, and writer in Java are considered traditional IO. Traditional IO is a blocking input and output, and is handled by byte movement, that is, traditional IO can only process one byte at a time and is inefficient.New IOBoth the new
First you need to knowWhat is Io:io is the input/output interfaceRead this article to take the following questions1. Cluster bottlenecks why IO?2. How much do you know about IO?This is only a personal point of view:When we are confronted with a cluster of operations, what we want is to be read. But in the face of big data, reading data needs to go through IO, whe

The answers given by different people in different contexts are different. So first limit the context of this article.This article discusses the background of networ
5 Types of IO modelsFive types of IO models under Linux(1) Blocking I/O: doing nothing, causing the application to block, waiting for data to be ready, if the data is not ready, blocking, etc. data is ready to be copied from the kernel to the user space(2) Non-blocking I/O: Set a socket interface to non-blocking, tell the kernel, when the requested IO cannot be c
. Although the 3 electric kettle is asynchronous, it does not make much sense for you to conforming. So asynchronous is generally used in conjunction with non-blocking, in order to play an asynchronous effect.5 IO Model under UNIX

Java 1.0 IO System Introduction1 Java IO versionThe IO of the Java library is divided into two parts: input/output.The early Java 1.0 version of the input system was inputstream and its subclasses, and the output system was outputstream and its subclasses.The later Java 1.1 version of the IO system was redesigned. The

The first thing to note is that the content of this article is not how to tune SQL Server query performance (about which you can write a book), but how to leverage the set STATISTICS IO and set STATISTICS in SQL Server query performance tuning Time these two frequently ignored Transact-SQL commands.On the surface, the adjustment of query performance is a very simple matter. In essence, we want queries to run as fast as possible, either by shrinking th
IO model1, blocking IO2, non-blocking IO3, multiplexing IO4, asynchronous IOOne, blocking IOThe blocking IO is characterized by a block of two phases of IO execution (two stages of waiting for data and copying data).Virtually all IO interfaces (including the socket interface) are blocking, unless specifically specified
Java IO producer stream and byte streamI. Basic Concepts
Stream: flows from one end to the other, from the source to the destination.Always centered on the program, it is a program and a file | array | Network Connection | database operations.
Ii. IO stream classification

Input stream and output stream
2. Data:
Byte stream: Binary. It can process text files, videos, and audios.Upload stre

These days to do the MySQL performance test, a huge company, find a few performance testing machines are very tangled, finally coordinated to two, IO performance is not known.The database is an IO-intensive application, so evaluate the server's IO performance first to see if it matches the machine on the line.I've always known that using the DD (device to device)
Brief introduction:Spring IO platform is the first item in the spring website. It integrates the core API of spring into a platform for modern applications. Provides version dependencies in the spring project portfolio. These dependencies are tested and can be guaranteed to work correctly.Why should I use it?Spring IO platform is primarily about resolving dependent version conflict issues. For a chestnut: i
