Thanks to everyone who was in attendance on 05 June 2013 for my “Choosing a MySQL HA Solution” webinar. If you weren’t able to make it but are interested in listening to the presentation, it’s currently up and available for viewing over at percona.com. My apologies if we weren’t able to get to your question […]
Swapping has always been something bad for MySQL performance but it is even more important for HA systems. It is so important to avoid swapping with HA that NDB cluster basically forbids calling malloc after the startup phase and hence its rather complex configuration. Probably most readers of this blog know (or should know) about […]
It’s Friday again, and time for another TGIF give-away of a Percona Live London ticket! But first, what’s new with the MySQL query cache? You may know that it still has the same fundamental architecture that it’s always had, and that this can cause scalability problems and locking, but there have been some important changes […]
We have a great line up of Tutorials on Percona Live, London. I hand picked number of them after seeing outstanding speaker Performance in other Places. Let me tell in little bit more details about people we have invited and their talks. Yoshinori Matsunobu Talk on Linux Hardware and Optimizations for MySQL at Oreilly MySQL […]

You need to know server internals, for example. You need to be able to do anything from optimizing difficult queries to moving high-volume services between data centers without interruption. Expert knowledge of […]
After having reviewed the definition my the previous post (The definitions), the next step is to respond to some questions. Do you need MySQL High-Availability? That question is quite obvious but some times, it is skipped. It can also be formulated “What is the downtime cost of the service?”. In the cost, you need to […]
As my first contribution to the MySQL Performance Blog, I joined Percona at the beginning September, I chose to cover the various high-availability (HA) options available for MySQL.Â I have done dozen of MySQL HA related engagements while working for Sun/MySQL over the last couple of years using Heartbeat, DRBD and NDB cluster and I’ll […]

A really nice person!
Yves joins us after a tenure of several years as a senior consultant at Sun/MySQL. Together with Matt Yonkovit, he plans to work on WaffleGrid (…
We had too many requests for deb builds of Percona releases so I could not ignore that and added scripts to build binaries on our Ubuntu 8.10 box. It’s going to be only 64bit releases (32bit is dead, isn’t it?), and I tested binaries on Debian Lenny system and it seems working fine. So I […]
Where does real power of MySQL Storage Engines, and pluggable storage engines as MySQL 5.1 lays ? It is very much advertised this allows third parties to create their own storage engines and we can see solutions as Solid and PBXT . Plus there is Falcon storage engine being developed inside MySQL. All of these […]
