How to achieve MySQL read-write separation.

There are several ways to achieve MySQL read-write separation:

1. Implementing read-write separation through MySQL master-slave replication: perform writing operations on the master server, and synchronize the update operations to the slave server for reading operations. Automatic synchronization can be achieved by configuring MySQL master-slave replication.
2. Implement read-write separation using middleware: By utilizing middleware such as MySQL Proxy or MaxScale, route write operations to the master server and read operations to the slave server.
3. Implementing read-write separation through an application: manually distributing read and write operations to different database servers within the application. Connection pooling or load balancers can be used to manage database connections.

Regardless of the method used, it is necessary to configure and adjust the application to ensure that read and write operations are correctly routed to different database servers.
