Twitter releases all MySQL scalability tweaks

Twitter has decided to release publicly all its MySQL scalable tweaks on Monday (Mar 09th). Publishing all the enhancements the company has made with the open-source database technology, which is responsible for all the data stored by Twitter.

"MySQL is the persistent storage technology behind most Twitter data: the interest graph, timelines, user data and the Tweets themselves," said Jeremy Cole and Davi Arnaut, two of Twitter engineers in a joint blog post, "Due to our scale, we push MySQL a lot further than most companies," they completed.

Some of the tweaks Twitter engineers have made to MySQL classic codes include optimization of memory allocation, allowing the database to work better in different memory situations and database usage for third-party apps integration.

The Twitter staff published most of the tweaks on a github.com/twitter/mysql.
