What Operating System do you run MySQL on in Production

This Friday we’ll have two polls instead of one to learn about Operating system we’re using to run MySQL. First Poll is about production use and second is about development. I know many developers would run MySQL on Linux in Production but use Windows or MacOS X for development. Please select operating system which actually […]

Realtime stats to pay attention to in Percona XtraDB Cluster and Galera

I learn more and more about Galera every day.  As I learn more, I try to keep my myq_gadgets toolkit up to date with what I consider is important to keep any eye on on a PXC node.  In that spirit, I just today pushed some changes to the ‘wsrep’ report, and I thought I’d go over […]

Percona XtraDB Cluster / Galera Tutorial at Percona Live NY 2012

I’ve mentioned this before, but I’m delivering a tutorial on Percona XtraDB Cluster / Galera at Percona Live NY 2012 right in midtown-Manhattan on October 1st. I really want this tutorial to be hands-on, not just a 3 hour lecture, so you can actually see how a cluster operates and interact with it.  So, I have come […]

During my webinar, a number of attendees asked some good questions.  Here are their questions and my […]

dbqp and Xtrabackup testing

So I’m back from the Percona dev team’s recent meeting.  While there, we spent a fair bit of time discussing Xtrabackup development.  One of our challenges is that as we add richer features to the tool, we need equivalent testing capabilities.  However, it seems a constant in the MySQL world that available QA tools often […]

The two even more fundamental performance metrics

In a recent blog post, I wrote about four fundamental metrics for system performance analysis. These are throughput, residence time, “weighted time” (the sum of all residence times in the observation period — the terminology is mine for lack of a better name), and concurrency. I derived all of these metrics from two “even more […]

Percona Server and XtraBackup Weekly News, April 25th

Time for our weekly review of the news! The big news this week is that Percona XtraBackup is ready to try out on Windows. Otherwise, there’s just more steady progress. One quick note, sort of a “to whom it may concern,” is that the proper trademarked names of our products include “Percona Server”, “Percona XtraDB”, […]

Percona Server and XtraBackup Weekly News, April 18th

Last week wasn’t so active in terms of new development, because many of us were at the MySQL conference, of course. However, we did push out the XtraBackup 1.6 release, and began work on backporting some features from MySQL 5.6 to 5.1 for a certain large customer. Several of the features we’ve added in 5.0 […]
