How to Clear the Slow Query Log on AWS RDS MySQL/ MariaDB

Here is a super simple little tip for clearing the mysql.slow_log in MySQL or MariaDB when running an RDS on Amazon AWS.

Luckily, the Amazon AWS team have put together a package that clears out the table for us. 

CALL mysql.rds_rotate_slow_log;
