Facebook announced on Thursday a new open source project called WebScaleSQL. The technology — a branch of the incredibly popular MySQL database — already includes contributions from Google, LinkedIn and Twitter, and Facebook promises the WebScaleSQL community will accept contributors from anyone with experience operating MySQL beyond its natural limits.
Facebook’s mastery of MySQL has been a point of pride within the company even as skeptics questioned the wisdom of sticking with the database. The last time I checked in, for a tech talk the company’s engineers gave in late 2011 (when Facebook was at a mere 800 million users), its MySQL environment was growing like crazy. Engineers talked about 60 million queries and 4 million row changes per second, and about rapidly multiplying data volumes. They also touched on the importance of flash storage, something the company has really picked up on during the ensuing couple of years.
