How It Affects Your App
MySQL 1794 ER_SLAVE_CONFIGURATION indicates that the slave server is not configured correctly. This can have a significant impact on an application as it can prevent the application from replicating data from the master server. This can lead to data loss or inconsistency between the master and slave servers. Furthermore, it can cause the application to become unresponsive or crash due to the inability to replicate data.
