History

The consortium grew out of a shared problem: companies running some of the world's largest MySQL deployments found that a stock distribution did not meet their scale-oriented needs. Each had maintained its own internal branch for years, reapplying custom patches whenever a new major MySQL release shipped. Rather than keep duplicating that effort, they chose to maintain a common set of changes together instead of separate branches and pool features they'd each developed independently.

Announced on March 27, 2014, the project was initiated by Facebook, Google, LinkedIn, and Twitter to consolidate these modifications. It was released under the GNU GPL v2, so others at a comparable scale could contribute. Alibaba Group joined in January 2015. In December 2016, the companies announced they would cease contributions, citing their differing needs, and the repository was archived that year.
