MySQL OPTIMIZE: Why & How to Use It

In MySQL, the OPTIMIZE command is used to improve the database table structure, enhancing query performance and decreasing storage space usage. When there are a large number of deletion and update operations in a table, it can lead to many empty spaces and fragments, affecting query performance and storage efficiency. By using the OPTIMIZE command, the storage structure of the table can be reorganized, with data rearranged, empty spaces and fragments removed, resulting in improved query speed and reduced storage space usage.
