Mysql resource limits.

0 votes
184 views

I would like to limit resources available to a given user in mysql. I know that there is https://dev.mysql.com/doc/refman/5.5/en/user-resources.html, I also know that cgroups can be used at operating system level.

What are your experiences in limiting resources in mysql? I've user percona statistics and had information provided by it. Are there any better solutions?

cgroups won't work for individual MySQL "users", only for mysqld as a whole.
Monitor the slowlog and help the naughty users fix their naughty queries.
