How It Affects Your App
This error indicates that the size of the binary log cache is larger than the maximum allowed size. This can cause the application to fail to write to the binary log, resulting in data not being stored in the database. This can lead to data loss and application instability, as well as potential security risks. Additionally, the application may experience performance issues due to the large size of the binary log cache.
