MySQL Master-Slave: Purpose and Benefits

The purpose of MySQL master-slave replication is to achieve data backup and read-write separation. By synchronizing the data from the master database to the slave database, data backup is achieved which improves data security. In addition, it allows read operations to be distributed to the slave database, reducing the load on the master database and enhancing system performance. Furthermore, master-slave replication can also be used for data analysis, data synchronization, and other applications.
