How It Affects Your App
This error indicates that the application is unable to replicate data between two MySQL servers due to gaps in the binary log. This can cause data inconsistency between the two servers, leading to incorrect results when querying the database. It can also lead to data loss if the application is not able to properly handle the inconsistency. This can have a significant impact on the application, as it may not be able to provide the expected results or may even crash due to the data inconsistency.
