A Brief Introduction to MySQL multi-source replication and mysql Replication Recently, ORACLE released several new features in the latest version of Mysql5.7.2. Most of the improvements are in terms of database performance and replication-related features. This new version will bring us incredible results. In this article, I will try to understand the working pri

Label:After performing your first instant recovery (pitr,point-in-time-recovery), we are ready to work on a real replication setup. In this chapter, you will learn how to set up asynchronous replication and flow. Our goal is to ensure that you can achieve higher availability and higher data security. In this chapter, we will discuss the following topics: • Configuring asynchronous

1. Replication overview1.1, Replication solution of the problem data replication technology has the following features: (1) data distribution (2) load balancing (load Balancing) (3) Backup (4) High availability (Hi availability) and fault tolerance1.2. How replication works from a high level,

OverviewRedis supports a simple and easy-to-use master-slave replication (Master-slave replication) feature that allows the slave server (slave server) to be an exact replica of the master server. Here are a few important aspects of the Redis replication feature: Redis uses asynchronous replication. Starting

Deep replication in Javascript and javascript Replication In javascript, the value assignment between all object variables is carried to the address. You may want to know which object objects are assigned. It may be better to give an example: Copy codeThe Code is as follows:Typeof (true) // "boolean"Typeof (1) // "number"Typeof ("1") // "string"Typeof ({}) // "object"Typeof ([]) // "object"Typeof (null) //

1. Master-slave replication1.1 PrincipleThe Main Library opens the Binlog function and authorizes the main library to connect from the library, obtains the relevant synchronization information from the library through change master, and then connects the main library for verification, and the main library IO thread is based on the request from the library slave thread. Starting from the location of the record Master.info start to fetch information, at the same time, the location point and the la

The original meaning of replication's English word is "copy", the replication file is the last file of my analysis in the data directory, enough to explain his importance, the code quantity 1800 +, indeed very difficult to chew. Can only say that I look at the code down the general impression of it, I want to draw a structural map to the various APIs in this diagram, which I can not really do at present.
