mysql replication tools

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. Th

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 to the powerful mysql

Asynchronous replication: MySQL natively supports one-way, asynchronous replication. Asynchronous replication means there is a delay in copying data from one machine to another-most importantly this means that the data cannot be copied/applied to the slave at the same time when the application's transaction commit has

I. Principles of MySQL master-slave Replication 1. mysql replication process: each time a write operation is executed, it will save a copy to its own database. At the same time, this write operation will also be stored in a binary log file, and save them as events. Therefore, each write operation or modification operat

performance of my system? MySQL replication can maximize performance in such a system: frequent read operations, infrequent write operations. In principle, with single-master and multi-slave scenarios, you can extend the system by adding slave to the bandwidth of the network, or your master cannot withstand the increased load of updates. To determine how many slave you want to use before you can stabilize
