MySQL 8.0 Query Rewrite supports SELECT INSERT UPDETE DELETE REPLACE statement rewriting

This feature needs to be liked. For example, when the developer went online, a SQL query field index was forgotten to fill up the online CPU. At this time, you can rewrite the SQL, let the business report an error first, don't kill the database, and then notify the developer to roll back immediately, and then go online after adding the index.

Install the plug-in
