MySQL replication is primarily replicated from the primary master. What is master-slave replication Master-slave replication means that there is a single device to do as the primary server, one or more servers as from the server. No data is written from the server, and the source of the data is the primary server. The purpose of the replication is to synchroniz

MySQL Replication We know that the binary log of the MySQL database records every clear or potentially changing SQL statement of the database. Therefore, we can achieve the master-slave consistency of mysql based on the binary log. The simple mysql replication process we mentioned here is:First, there is a dump thread on the mysql Master server, which reads binary logs and sends them to slave.Then, mysql ha

Overview replication is usually used to create a copy of the master node to ensure high availability by adding redundant nodes. Of course, replication can also be used for other purposes, such as reading and analyzing data on the slave node. In horizontally Scalable businesses, replication is easy to implement, mainly in the use of the master node for write operations, multiple slave nodes for read operatio
