It’s August 1st, 2011, and five years ago on or about this date (who can remember clearly?) Peter Zaitsev and Vadim Tkachenko founded Percona. What’s happened in the last five years?

We’re a privately held, privately funded company of over 50 employees distributed globally, serving 1200 customers worldwide with support, consulting, training, and engineering services for MySQL. Our revenue isn’t public, but we’re proud that we’re able to keep all those people busy and help provide for their families. We’ve contributed significantly to improved performance and advanced functionality in the MySQL server and InnoDB storage engine, and created the first and only opensource hot-backup tool for InnoDB, as well as many other open-source software engineering projects.

We’re happy that we’ve …

Codership team announced availability of MySQL/Galera 0.8.1, which is minor release, but actually it has bunch of improvements that makes Galera replication more user friendly (there are many bugs fixed, reported by me personally, what annoyed me a lot).

As part of my evaluation activity I ported MySQL/Galera 0.8.1 to Percona Server/Galera 0.8.1 and you can get source code on Launchpad.

I appreciate the fact that not everybody has fun from compiling source code (hint, hint for Drizzle developers), that is why I also made binaries for RHEL 6.1 / Oracle Linux 6.1

A while back, I wrote a two part post on how you can extract an amazing amount of information about a system’s performance, scalability, queueing, and more by just measuring request arrivals and completions, and the timestamps thereof.

I promised to develop this into a more complete description of how to analyze MySQL’s performance and scalability through nothing more than TCP/IP packet headers. I presented the results of that research at Percona Live in New York City, and the slides and video are online. The video editors didn’t synch the slides …

I’m speaking at the great multi-speaker MySQL Meetup event taking place in London, 18th of July.
I’ll talk about approaches to application scalability which is one of my favorite topics and would be a good fit both for MySQL DBAs and Developers. Make sure you register on meetup page as otherwise you will not be able to get into the building.

As an extra bonus I will give away couple of tickets to the Percona Live, London scheduled for late October. Must to attend conference if you’re serious about MySQL.

Hope to see you there !

On July 12th at 9 AM PST I will be giving a webinar about performance implications for Hibernate and Connector/J. If you cannot attend at this time, a recorded session will be available soon after the webinar.

MySQL is not only about LAMP, and a lot of people use it from Java apps. For some of those, Hibernate is the persistent framework of choice. This webinar will discuss the performance implications of using Hiberate to manage persistence with a MySQL backend, and also some more broad implications for Connector/J  that will apply for anyone using MySQL from Java.

Topics will include:
* Very brief overview of ORMs and Hibernate
* Fetch strategies
* Lazyness
* Manually written SQL
* Concurrency
* Concurrency-related config options for Connector/J

You may register …

Percona is pleased to welcome Stewart Smith to the team. Stewart does not need an extended introduction for MySQL Community, but just in case: Stewart has a long history with both the MySQL and Drizzle code bases. He’s been one of the core Drizzle developers since the start of the project (working on Drizzle for Sun and then Rackspace), he maintains HailDB and previously worked for MySQL (and then Sun) on MySQL Cluster (NDB).

Stewart joins Percona to lead our development team and will take lead role in both Percona Server and Percona XtraBackup products. You can certainly expect more mutual exchange of features and ideas between Drizzle, …
