MySQL/MariaDB query timeout - use cron
0  2K+ {{}}
Okay, so if you ever worked on a big project, and you had to manage some DB, regardless of storage engine, have you wondered what happens if some big *sql query occurs? Well for MySQL/MariaDB there is no timeout on a query, so you are on your own.

To be honest, this is not a rocket science, but you will save yourself from a lot of trouble in the future, if you only write a simple bash/perl script which runs on crobjob once in a while.

If you don't know bash, this script is very useful.
This should go in your cronjob:
* * * * * root /your/path/to/script -t 200 -s -K

Where -t is param for time, in seconds, therefore this will kill any query which runs longer than 200s.

If you are not familiar with crontab, read this asap.
