How It Affects Your App
The impact of MySQL 1616 ER_DELAYED_NOT_SUPPORTED on an application is that it prevents the application from using the DELAYED keyword when inserting data into a table. This means that the application will not be able to take advantage of the performance benefits of delayed inserts, which can be significant when dealing with large amounts of data. As a result, the application may experience slower performance when inserting data into a table.
