How It Affects Your App
This error indicates that a switch of the binary log is not allowed while a transaction is in progress. This can have a significant impact on an application, as it prevents the application from switching to a different binary log while a transaction is in progress. This can lead to data integrity issues, as the application may not be able to write all the data to the correct binary log. Additionally, it can lead to performance issues, as the application may not be able to switch to a different binary log in order to optimize performance.
