How It Affects Your App
This error indicates that the application is using a version of MySQL that does not support the slave_preserve_commit_order option. This means that the application may not be able to guarantee that transactions are committed in the same order on the master and slave databases. This could lead to data inconsistency between the two databases, which could cause errors in the application. Additionally, the application may not be able to guarantee that transactions are committed in the same order on the master and slave databases, which could lead to data integrity issues.
