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 opera

IntroductionGtid is a global transaction ID that has been successfully executed based on the original MySQL server, combined with the server ID and transaction ID. This global transaction ID is unique not only on the original server, but also on all MySQL servers where the master-slave relationship exists. It is this feature that makes MySQL
