How It Affects Your App
MySQL 1380 ER_RELAY_LOG_INIT is an error that occurs when the relay log initialization fails. This error can prevent the application from running properly, as it is unable to properly communicate with the database. This can lead to data not being stored correctly, or not being stored at all. It can also lead to the application not being able to access the data it needs, leading to unexpected errors or crashes.
