Percona Server with XtraDB Case Study, Behind the Scenes

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 different techniques to diagnose. This can be hard when the …

Percona White Paper: Architecting SaaS Applications with XtraDB

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 valuable suggestions that made the white paper better.

Percona Launches New Support Option for MySQL

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.

1. Sensible Pricing

We've always offered pay-as-you-go support, and we've had a dedicated support staff for a while. The missing ingredient was flat-rate pricing. Big …

Percona Server 5.1.49-rel12.0

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.

Starting with this release, we will also provide special …
