only one SQL thread in the slave database to execute write operations. In the long run, the gap between the slave database and the master database will grow bigger and bigger. In this case, multiple SQL threads can be started from the slave database to execute write operations. Each thread is responsible for executing all related transactions of a database in the master database. In addition, after a transaction is committed on the master database, the related records are not synchronized to th

How to configure MariaDB replication in CentOS Linux This is a process of creating duplicate database versions. The replication process not only copies a database, but also synchronizes changes from the master node to a slave node. But this does not mean that the slave database is the same as the master database, because repl

ObjectiveBackup database is the first task in production environment, sometimes have to replicate the database through the network, because the master-slave copy of MYSQL/MARIADB is transmitted in plaintext, if it is transmitted across the network in production environment, the security of data cannot be guaranteed completely, in order to solve this problem, We need a secure way to transmit data, which is based on SSL encryption.Deployment Configurati
