I've a spring app with hibernate which is connected to MariaDb. When I try to perform some delete operation using NativeQuery on a table I'm getting java.sql.SQLException: Deadlock found when trying to get lock; try restarting transaction this exception.
I don't get this exception everytime, looks like it is happening only when we have lot of requests that performs the delete operation.
