Slow queries can be annoying, but the good news is that we can identify and fix them. Identify and analyze slow queries in MySQL In the following sections, we will see how we can get information about the default execution plan and explore ways to optimize our queries to influence the plan. The MySQL server sends the results to the MySQL client.The Query Execution Engine executes the plan by making calls to the Storage engine through special handler interfaces.The optimizer may ask the Storage engine for statistics about the tables referenced in your query before execution. The query is parsed, preprocessed, and finally optimized into a query execution plan by the MySQL query optimizer.The MySQL client sends your query to the MySQL server using the MySQL Client/Server Protocol. These steps are complex internally but can be summarized below: Understanding how these steps work can unlock powerful insights into how you can optimize your queries. MySQL processes your query in a series of steps.
