Welcome to the Twitter MySQL wiki! Twitter MySQL changes are primarily focused on making the day-to-day administration of MySQL easier and to improve the predictability of Twitter's services around MySQL. It is our intention to push changes upstream as much as possible. Contact us on GitHub or file any issues if you have questions.
