What’s the connection between databases and fruit flies?
Some of you may be familiar with the bestseller in business literature The Innovator's Dilemma: When New Technologies Cause Great Firms to Fail, by Harvard professor Clayton Christensen. In his book, Prof. Christensen compared disk drives to fruit flies. The comparison relates to the rapid changes that disrupted the disk drive industry for decades. That disruption is compared to the rapid changes that take place to fruit flies that live only for few hours, and for this reason researchers can study and analyse their behaviour.

In the software business, you can replace disk drives with databases. Obviously, databases live longer than fruit flies, but it is an industry that sometimes shows schizophrenic changes. Whilst it is true that relational databases have being dominated the scene for decades, readers with grey hair and reading glasses have …

On Thursday MySQL technology saw a huge boost. It’s hard for anyone now to argue that MySQL isn’t in the game of extreme scalability and performance, which some NoSQL vendors have been using as a tagline for the last years. To see four of the largest MySQL and MariaDB users come together to bootstrap a branch of MySQL for extreme scaling needs is simply fantastic. The improvements done inside these companies will now be available to the rest of the community. In all fairness Facebook and Twitter, in particular, have been making their improvements publicly available also before. Google has also made some improvements available publicly over the years and have lately been active in the MariaDB project with code reviews, bug fixes and other patches. But broadening the public contributions further and combining it all, is new.

Engineering of MySQL technology happens in many places. Aside from Oracle and the companies behind WebScaleSQL, …
