How It Affects Your App
MySQL 1565 ER_DDL_LOG_ERROR can have a significant impact on an application. It indicates that an error occurred while writing a DDL statement to the binary log. This can prevent the application from executing the statement, which can lead to data inconsistency and data loss.
