Ubuntu Online Summit: MySQL & Variants in 16.04
+0 Vote Up -0Vote Down

I personally have always enjoyed the Ubuntu Developer Summits (UDS), but nowadays they have been converted to the Ubuntu Online Summits (UOS). Attending them is not always convenient (timezone issues, might be travelling, etc.) so I watched the recorded video of a session I was interested in: MySQL & Variants in 16.04.

My key takeaways

  1. Ubuntu 16.04 Xenial Xerus is an LTS release.
  2. The term “cross-grade” is used a lot (it is not about downgrading/upgrading, but being able to use MySQL or MariaDB …

Recently at Percona Live Amsterdam I gave a talk titled Databases in the Hosted Cloud (I’m told I got a 4/5 rating for this talk). It was before AWS re:Invent, so obviously some of the details in the talk have changed. For one, now there is also Amazon RDS for MariaDB. But there has also been other changes, i.e. …

Percona Server audit log plugin best practices
+0 Vote Up -0Vote Down

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.

We have seen attempts at creating audit trails using approaches such as ‘sniffing the wire’, init files, in-schema ‘on update’ fields, triggers, proxies and trying to parse the traditional logs of MySQL (slow, general, binary, error). All of these attempts miss a piece of the pie, i.e. if you’re sniffing …

super_read_only and GTID replication
+0 Vote Up -0Vote Down

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!

TL;DR

Enabling super_read_only on all slaves when using GTID replication makes your topology far less sensitive to errant transactions. Failover is then easier and safer because …
