The data synchronization function of mysql not only provides load balancing for database queries to a certain extent, but also provides great help for database redundancy, backup, recovery, and load balancing. The data synchronization function can be implemented through master-slave replication, while master-slave replication is performed asynchronously. mysql only supports one

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

The master-slave replication structure of MySQL is different from the master-slave replication structure. In the master-master replication structure, any changes to the data inventory on one of the two servers will be synchronized to the other, so that the two servers are mutually
