Percona Server audit log plugin best practices

Auditing your database means tracking access and changes to your data and db objects. The Audit Log Plugin has been shipped with Percona Server since 5.5.37/5.6.17, for a little over 12 months. Prior to the Audit Log Plugin, you had to work in darker ways to achieve some incarnation of an audit trail.

Testing MySQL partitioning with pt-online-schema-change

There are cases where we need to implement MySQL partitioning, or at least test if it is an option to solve an issue. However, how are we able to test it when the table on our production environment has hundreds of millions of rows, several composite indexes and/or the size on disk is hundreds of gigabytes?Testing environments usually don’t have all the data that production has and if they have, probably you are not testing all the use-cases at a database level. Therefore, is it possible to test MySQL Partitioning on production impacting as less as possible?

super_read_only and GTID replication

Percona Server 5.6.21+ and MySQL 5.7.8+ offer the super_read_only option that was first implemented in WebscaleSQL. Unlike read_only, this option prevents all users from running writes (even those with the SUPER privilege). Sure enough, this is a great feature, but what’s the relation with GTID? Read on!

Percona Toolkit and systemd

After some recent work with systemd I’ve realized it’s power and I can come clean that I am a fan. I realize that there are multitudes of posts out there with arguments both for and against systemd but let’s look at some nice ways to have systemd provide us with (but not limited to) pt-kill-as-a-service.
