Erin and Mike, organizers of SF Meetup generously invited me to talk on coming SF Meetup on Dec-14 about new features in InnoDB in MySQL 5.1 and 5.5 and, what is pay attention to, when you upgrade from MySQL 5.0.

Percona white paper: Forecasting MySQL Scalability
+3 Vote Up -1Vote Down

Ewen and I have just published Percona’s latest white paper, Forecasting MySQL Scalability with the Universal Scalability Law. This is essentially a streamlined walk-through of Dr. Neil J. Gunther’s book Guerrilla Capacity Planning, with examples to show how you can apply it to MySQL servers.

One thing alluded to in the paper is extracting the necessary metrics from network traffic. I had this idea after studying the data in Linux’s /proc/diskstats file. It turns out that two simple metrics can provide amazingly rich insight into system performance and scalability, in combination with Little’s Law and queueing theory. These are the busy time and the total time that requests were resident in the system. There are different terms for the

Register now for a free Percona webinar about migrating your MyISAM databases to InnoDB. Save the date: Dec 1, 2010 at 9:00 AM PST (California) time.

Update: the date was originally listed as December 2nd, but that was a mistake. It's December 1st.

We know that not everyone can attend expensive conferences that require travel. We're going to be doing highly technical webinars regularly, to help those people get some of the same kind of content they might get at the conferences where we present. This is our first such webinar.

With the change in default storage engine from MyISAM to InnoDB in the upcoming MySQL 5.5 release, we expect that a lot of users will be wanting to learn more about the benefits of switching to InnoDB, as well as topics such as:

Baron Schwartz interviewed on WebPulp.tv
+0 Vote Up -1Vote Down

There's an interview with Baron Schwartz (that's me) on WebPulp.tv. Topics include the history of Percona's software such as Percona Server (our version of the MySQL database server) and XtraBackup, what we do at Percona, what tools we use to do it, how to think logically about performance optimization, what ugly surprises happen when you set up mysqldump backups and forget about them for a couple of months, and lots of other things. If you have not watched past episodes, I encourage you to do that. They feature a lot of really smart people from companies such as New Relic and 37signals. Josh is a great host for the show. He's a web engineer himself, and he knows how to ask probing questions that bring out a lot of

Percona Server with XtraDB Case Study, Behind the Scenes
+5 Vote Up -2Vote Down

We've published our first case study. The customer, ideeli, had a database that was struggling on standard MySQL and InnoDB. The big win was the upgrade to XtraDB. The business continued to grow quickly, and months later under much more traffic, the database is still outperforming their previous version.

I thought I'd write a few notes that didn't seem appropriate to include in the case study, because this was a fun project that might be interesting to readers.

As usual, it was all about diagnosing the problem correctly. I used a variety of tools to help with this, foremost among them "stalk" and "collect" from Aspersa. There were several problems, not just one, and they required

Percona White Paper: Architecting SaaS Applications with XtraDB
+2 Vote Up -1Vote Down

Vadim and I have just published a new technical white paper. It shows how Percona Server with XtraDB can make large-scale multi-tenant databases easier to build with MySQL. Our experiences working with SaaS and shared-hosting companies influenced the features we included in Percona Server and XtraDB, and I think this is the best explanation of what levers are available and how to use them.

Percona Server with XtraDB for Software-as-a-Service Application Databases is posted on the white-paper section of our website. No registration is required; it is just a PDF, freely downloadable with no marketing follow-up. Many thanks to Mark Callaghan and Dimitri Kravtchuk, who reviewed and gave

Percona Launches New Support Option for MySQL
+8 Vote Up -7Vote Down

We've just announced a new support offering for MySQL. There's a press release here, and product information page here. But what does this new service really mean for you, in practical terms? This is actually important -- it will open up a range of new choices for you. I'll explain two major points that matter to you.

Before I begin, I want to make it clear that in some ways, what we're offering is something we've always offered. That is actually why it took us a while to re-align the product a bit. We thought we were serving you fully. You told us that wasn't really true. Thank you. We've listened.

Percona Server 5.1.49-rel12.0
+3 Vote Up -0Vote Down

Dear Community,

Starting with this release, we introduce a new release model for Percona Server. From now on, we will have both Stable and Release Candidate releases. Release Candidates will introduce new features not yet available in Stable releases.

Along with new features, our new 5.1.49-12.0 RC contains a couple of patches from the Facebook-MySQL tree - https://launchpad.net/mysqlatfacebook . Of particular note is better integration with FlashCache.

We also introduce the very interesting new feature called ”Permanent InnoDB Buffer Pool”  (sponsored by a Well Known Social Network site). It allows you to keep the InnoDB buffer pool in memory between restarts of MySQL servers.
This can result in a significant decrease in warmup time after MySQL restarts.
