If a filepath is defined and reading the file fails (like if the path does not exist), then the database creation will fail.

If set to "OFF", the MySQL X Plugin will not initialise. If set to "FORCE", the MySQL Server will either start up with the MySQL X Plugin guaranteed to have successfully initialised, or if initialisation fails, the server will fail to start up.

+#### Init SQL file order of operations:
+
+There are some SQL queries executed on the database before the database is ready to be used. This is handled under the hood using the ```--init-file``` MySQL server option. Learn more at the [--init-file MySQL Documentation](https://dev.mysql.com/doc/refman/8.4/en/server-system-variables.html#sysvar_init_file). The following is the order in which the SQL queries are executed in, ordered from first executed to last executed:
+
+1. ```mysql-memory-server``` internal SQL queries - The internal queries that are executed are creating the MySQL user with ```options.username``` username if the option's value is not ```root```, and creating a database with the ```options.dbName``` name.
+2. The SQL queries provided to the ```initSQLString``` option
