mysql replication types

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

the master server and those on the slave server.1.1 mysql supports the following replication types: (1) Statement-based replication: SQL statements executed on the master server and the same statements executed on the slave server. MySQL uses statement-based

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
