Scaling Twitter with MySQL
Best Practices for Businesses
4 April 3:00PM - 3:50PM @ Ballroom D
50 minutes conference
MySQL is the data storage technology behind most Twitter data: the social graph, timelines, users, direct messages, as well as tweets themselves. With more than 200 million monthly active users and 500 million tweets per day, Twitter pushes MySQL and InnoDB a lot further than most companies. This talk will cover the data storage architecture at Twitter and how the architecture has evolved to meet Twitter’s needs. We will also discuss the challenges Twitter is facing in this area.
