If you attended last April’s Percona Live MySQL Conference and Expo in Santa Clara, you know it was a rare opportunity to learn from some of the most accomplished system architects and developers in the business. Now it’s time to give back.

The call for papers (CFP) is now open for Percona Live London, November 11-12 at the Millenium Gloucester Conference Center. Login or register as speaker and submit your proposals.

Your participation is an opportunity to make a difference. After all, the conference would be meaningless without great content. So step up and volunteer to present your unique insights into MySQL and MySQL-related technologies either as a …

Overview

First off, the important news. Tungsten Replicator 2.1.0 was released today.
You can download it and give it a try right now.

Second, I would say that I am quite surprised at how much we have done in this release. The previous release (2.0.7) was in February, which is just a few months ago, and yet it looks like ages when I see the list of improvements, new features and bug fixes in the Release Notes. I did not realized it until I ran my last batch of checks to test the upgrade from the previous release, which I hadn’t run for quite a long time. It’s …

A blog post is a composition in an informal verse, usually characterized by the sharing of ideas, experiences, and opinionated news. This vivid explanation of valuable ramblings about the database technologies is what makes this Log Buffer Edition again.

Join 6100 others and follow Sean Hull on twitter @hullsean. There are two ways to speedup UNIONs in a MySQL database.

Taxonomy upgrade extras: galeraclusterMySQL ClusterHigh Availability

Recently we had to set-up a 3-node Galera Cluster with a Load Balancer in front of it. Because Galera Cluster nodes (mysqld) still reply to TCP requests on port 3306 when they are expelled from the Cluster it is not sufficient to just leave it to the Load Balancer to check the port if a Galera node is properly running or not.

We used the wsrep_notify_cmd variable to hook our own script into the Galera Cluster which disables each Node on the Load Balancer when its state …

Are you a Django user? There’s an upcoming Django conference in Chicago in a few months, and I know they’re looking for speakers with MySQL experience in particular. One suggestion the organizers have floated is a talk on MySQL:

I’m looking for someone to give at least one MySQL talk there. In particular, I would love a (friendly but vigorous) “Why you should use MySQL instead of PostgreSQL talk”, as PostgreSQL tends to get a lot of love and attention at Django events, and MySQL not so much.

Take a look at it and see if you are interested. Presenting at a conference is one of the best things you can do for your career, your company, and your community of open-source software. I highly encourage it if you haven’t tried it.

Subject says its all, this is of course, very good news coming out of the Red Hat Summit. Looking forward to Red Hat Enterprise Linux 7. And of course, CentOS 7 and the other builds that follow. Thank you Red Hat!
