Fix High MySQL Memory Usage

If the memory usage of MySQL is too high, you can try the following methods to solve it:

1. Optimize database configuration by checking the MySQL configuration file and adjusting parameters such as buffer size and connection numbers to reduce memory usage based on the actual situation.
2. Optimize the search queries to avoid unnecessary full table scans and index scans, improving query efficiency and reducing memory usage.
3. Regularly clean up cache: Regularly clean up MySQL cache, including query cache, table cache, etc., to free up memory space.
4. Analyze and optimize table structure: Optimize the table structure based on actual circumstances, design indexes reasonably, and reduce memory usage during queries.
5. Utilize a MySQL monitoring tool to keep track of database performance and memory usage, promptly identifying issues and making adjustments.
6. Upgrade hardware: If the above methods do not solve the issue, consider upgrading the server hardware by increasing the memory capacity.

By optimizing the memory usage of MySQL through the above methods, it can greatly enhance the performance and stability of the database.
