master clips

The ultimate goal of data replication is to synchronize the data of one server with the data of another server, which can achieve data redundancy or load balancing of services. A master server can connect multiple slave servers, and the slave server can act as the master server in turn. The master-slave server can be located in different network topologies. Due t

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
