The MySQL team is looking for external contributions! Have you written a piece of code that would benefit everyone? Would you like to see it in the main distribution of the world’s most popular database? The process is simple and quick. Get in touch with our engineers or community managers to discuss the nature of your contribution and any technical details (via conferences, blog, bugs, or any other way), and then fill out a one pager called the Oracle Contributor Agreement. We welcome community feedback in the form of code, comments, or bugs. Thank you in advance for getting involved!
So if you have something you want to change in MySQL or a new feature, download the source code and get cracking!
And do not forget the MySQL Worklog where you can give your input on future features and design trends.
