How It Affects Your App
MySQL 1398 ER_XAER_INVAL has a significant impact on an application. It indicates that an XAER_INVAL error has occurred, which means that the transaction has been rolled back due to an invalid argument. This can cause data inconsistency and data loss, as the transaction is not committed to the database. It can also lead to application downtime, as the application may need to be restarted in order to recover from the error. Furthermore, it can cause performance issues, as the application may need to re-execute the transaction in order to complete the operation.
