How do you optimize database schema design for performance in MySQL?
Article Introduction：Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

Approaches to Scaling MySQL Database for High Load
Article Introduction：The MySQL stand-alone bottleneck can be solved through read and write separation, library separation, cache and asynchronous processing and other optimization methods. 1. Read and write separation is realized through master-slave replication. The main library processes write requests, and the slave library processes read requests, and combines connection pools to improve efficiency, but attention should be paid to the asynchronous replication delay problem; 2. The sub-repository sub-table includes vertical split (split by field) and horizontal split (split by rules), which is suitable for large data scenarios and requires middleware to handle complex queries; 3. Caching can reduce database pressure, use Redis or Memcached to cache hotspot data, and combines message queues to asynchronously process non-real-time write operations; 4. Other optimizations include slow query analysis, parameter tuning, connection pool management and SQL optimization, and detailed processing is crucial to performance improvement.

Action Automation with MySQL Triggers
Article Introduction：Core points
MySQL triggers simplify PHP projects with automated operations such as database queries, file operations, and data processing. They are automatically called before or after actions (insert, update, delete) on the table.
Triggers were introduced in MySQL version 5.0.2 and required corresponding permissions to be created. They must have a unique name in the database where they are created and will only be fired when the original SQL statement is executed.
Triggers help maintain the integrity of a set of tables, automatically increase or decrease statistical tables when new inserts/deletes, record changes to data within the database, and keep tables synchronized with other tables.
MySQL triggers can have a positive impact on the performance of your website and allow developers to write a lot of P
