1.2 Different types of replicationNow that you have completely understood the limitations of physics and theory, you can start learning different types of replication.1.2.1 Synchronous and asynchronous replicationThe first distinction we can make is the difference between synchronous replication and asynchronous replication.What does that mean? Suppose we have two servers and want to replicate data from one

Article Summary: Oracle is a database platform, and some projects use Oracle's database replication technology, which also encounters some problems, so here I have a personal understanding of Oracle's replication technology, hoping to help the project team with Oracle databases.

Three modes of MySQL replicationMySQL currently has three replication modes: asynchronous mode, semi-synchronous mode, and group copy mode, first understand how the three modes work.1. MySQL Asynchronous Replication (asynchronous replication)Asynchronous replication is the oldest and most currently used

For a geographically dispersed large enterprise organization, to build a large enterprise management information system with typical distributed computer features, it is always necessary to solve a very important problem: how to ensure the consistency of shared data among different database servers. The important problem is that the organization changes the local database with the same structure in different locations, but it is necessary to ensure that the modified database has the same result,

Label:13th. The extensible design of MySQL Replication Objective: MySQL Replication is a very distinctive feature of MySQL, and he is able to copy the data from one MySQL server Instance to the Instance of another MySQL server. Although the replication process is not real-time but asynchronous, due to its efficient performance design, latency is very small. MySQL
