Sponsoring the Apache Foundation

Open source is a pervasive part of our culture. Many projects at Twitter rely on open source technologies, and as we evolve as a company, our commitment to open source continues to increase. Today, we are becoming an official sponsor of the Apache Software Foundation (ASF), a non-profit and volunteer-run open source foundation.

MySQL at Twitter

MySQL is the persistent storage technology behind most Twitter data: the interest graph, timelines, user data and the Tweets themselves. Due to our scale, we push MySQL a lot further than most companies. Of course, MySQL is open source software, so we have the ability to change it to suit our needs. Since we believe in sharing knowledge and that open source software facilitates innovation, we have decided to open source our MySQL work on GitHub under the BSD New license.
