Persisting Configuration VariablesIn the next major release of MySQL (8.0) we also introduce a new feature which allowconfiguration variables to be persisted.

This means that for a number of configuration settings, you will no longer need tomanually edit a configuration file and can instead make modifications directly via an SQLconnection.

mysql> SET PERSIST innodb_buffer_pool_size = 512 * 1024 * 1024;Query OK, 0 rows affected (0.01 sec)

mysql> SET PERSIST max_connections=500;Query OK, 0 rows affected (0.00 sec)
