Composite indexes are useful when queries involve multiple columns. Use the following syntax:

SELECT * FROM performance_schema.events_statements_summary_by_digest
ORDER BY SUM_TIMER_WAIT DESC
LIMIT 10;

MySQL Workbench provides a graphical interface for monitoring database performance. It includes tools for visualizing server status and performance metrics.

Regularly review query performance and make adjustments as necessary. Use tools like MySQL Workbench, Percona Toolkit, or performance_schema for ongoing monitoring and optimization.

Optimizing MySQL queries is a continuous process that requires understanding and applying best practices. By using indexes effectively, analyzing queries with EXPLAIN, and refining your SQL statements, you can significantly enhance the performance of your MySQL databases. Regular monitoring and adjustments will ensure your applications run smoothly and efficiently.
