You probably saw the Twitter storm over Oracle's pricing changes and InnoDB in the last few days. The fear about Oracle removing InnoDB from the free version of MySQL was baseless -- it was just a misunderstanding. Still, in the years since MySQL has been acquired by Sun, and then by Oracle, many MySQL users have been uncertain about the future. We think it's important for us to make our own position and plans clear and public, so that there is no fear or doubt about what Percona will do.

We want to begin by saying "thank you" to those who built and maintained MySQL over the years. Many of us at Percona came from the original MySQL team. We know that it took a decade-long group effort from Monty, David, Marten and many others to develop it into the world's leading open-source database. Much of their work is never publicly recognized, but it is the foundation of our own work, and we're indebted to it. MySQL development suffered some detours …

Oracle has released news about changing policies of MySQL Enterprise Support effectively dropping annual support for Basic and Silver. The entry level support is now $3000 per server per year. The MySQL support team now part of Oracle has great resources however Oracle is in the business of making money. When a general company question for OOW is company income, and the first option is < $50 million it highlights that startups, and smaller companies are clearly not a focus.

The success of MySQL as an open source company has lead to other leading providers that now can provide enterprise level support. More importantly many organizations over per-incident support which is more cost effect. News in the past week has included Percona - …

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 …
