A week ago we launched our first GA release of Percona Server 5.6 and it’s a real game-changer for us. The release of Percona Server 5.6 (our enhanced, drop-in replacement for MySQL) not only provides stability and performance but also provides key features only available in Oracle’s MySQL 5.6 Enterprise Edition. As usual, Percona Server […]

Experimental Git mirror of Oracle MySQL trees

I’ve been working on setting up mirrors on github of all our BZR branches. My first efforts that are at a suitable stage to share are mirrors of the Oracle MySQL trees. This is currently a snapshot of MySQL 5.1, 5.5 and 5.6 with all the tags preserved. I’ve managed to get GIT to compact […]

Percona Server 5.6 Webinar follow-up and Q&A

Good news everyone! I recently presented a webinar: Percona Server 5.6: Enterprise Grade MySQL. It was also recorded so you can watch along or view the slide deck. As with all my talks, I am not simply reading the slides so it really is worth to listen to the audio rather than just glance through […]

Understanding the maximum number of columns in a MySQL table

This post was initially going to be two sets of polls: “What is the maximum number of columns in MySQL?” and “What is the minimum maximum number of columns in MySQL?”. Before you read on, ponder those questions and come up with your own answers… and see if you’re right or can prove me wrong! […]

Serious build and testing automation

Here at Percona we’ve spent a lot of time improving our development and testing practices. Why? Because constant innovation keeps us ahead and more productive. We want to work smarter, not harder. One of the tools we use is the Jenkins Continuous Integration server. We use Jenkins pretty heavily to help with out development processes […]

Percona response to recent MySQL security bugs

Recently there have been discussions on several vulnerabilities in MySQL and closely related projects such as MariaDB and Percona Server. Usually we have inherited security fixes from MySQL when we have updated Percona Server to be based off a new Oracle MySQL release. In this case however, Oracle has been incredibly quiet. We’ve been examining […]

A (prototype) lower impact slow query log

Yesterday, over at my personal blog, I blogged about the impact of the MySQL slow query log. Since we’re working on Percona Server 5.6, I did wonder if this was a good opportunity to re-examine how we could provide slow query log type functionality to our users. The slow query log code inside the MySQL […]

Where to get a BZR tree of the latest MySQL releases

I just posted this to the MySQL Internals mailing list: Hi all, Like many of you, I’m disappointed that the bzr trees for MySQL are out of sync with the tarball source and binary releases from Oracle. Since Oracle has been silent on this, and this is a recurring problem, I’ve decided to attempt to […]
