In phpMyAdmin, the Optimize Table feature is beneficial when removing a substantial portion of a table or modifying tables with variable-length rows, such as those containing VARCHAR, TEXT, BLOB, or VARBINARY columns. Deleted rows are stored in a linked list, allowing new insert operations to reuse their space. Optimizing the table helps reclaim unused space and defragment the data file, improving overall efficiency. This process can significantly enhance performance for tables that experience frequent updates or changes.
