MySQL read-write separation is achieved by assigning read and write operations to different MySQL instances.<\/p>\n

There are two common implementation methods:<\/p>\n

    \n
  1. Implementing read-write separation through MySQL proxy server.<\/li>\n
  2. Configure a read-write separation rule on the MySQL proxy server to route read and write operations to different MySQL instances based on the type of SQL statement.<\/li>\n
  3. Read operations can be distributed to multiple read-only MySQL instances through a load balancing algorithm to improve read performance.<\/li>\n
  4. Write operations are only forwarded to the master MySQL instance to ensure data consistency.<\/li>\n
  5. Commonly used MySQL proxy servers include MySQL Proxy and MaxScale.<\/li>\n
  6. Implementing read-write separation using application layer code.<\/li>\n
  7. Manually switching database connections in application layer code based on the type of SQL statement.<\/li>\n
  8. For read operations, connecting to a read-only MySQL instance allows for evenly distributing read requests through a load balancing algorithm.<\/li>\n
  9. When performing write operations, ensure data consistency by using the connection to the primary MySQL instance.<\/li>\n
  10. This method requires explicit management of database connections in the application layer, which can be cumbersome but offers greater flexibility.<\/li>\n<\/ol>\n

    Regardless of the method used to achieve MySQL read\/write separation, the following points need to be considered:<\/p>\n

      \n
    1. Database master-slave synchronization: Write operations on the master database need to be synchronized with the slave database to ensure data consistency.<\/li>\n
    2. Database connection management: it involves managing the creation, shutdown, and usage of connection pools in order to improve performance and resource utilization.<\/li>\n
    3. The logic of database switching involves determining when to use a read or write database based on business needs, and how to handle potential data inconsistencies when switching between reading and writing.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
