Biography

Originally wanting to become the next Angela Merkel, Lilli Seyther-Besecke discovered her passion for software development workflows and how to improve them early on at London-based startup Yieldify. During her time at GitHub, she led many customers through their transformation process towards agile development and inner sourcing.

From GitHub to PlanetScale – How Schema Changes and Pull Requests Go Hand in Hand

When Linus designed Git, one of his famous quotes was “branching is not the problem, merging is”. Properly merging database schema changes along with code is even harder – especially if many teams and terabytes of data get involved. Lilli will tell how those challenges got addressed at GitHub and how the same tooling found its way into PlanetScale’s database branching and merging workflow. The main part of the talk will be a live demo showing how to propose, test, approve and merge MySQL schema changes directly from a pull request along with the corresponding application code changes. You will also learn the story behind Vitess – the Open Source project invented by the founders of PlanetScale to reliably run MySQL at YouTube – now used in production environments at places like Slack, GitHub, Roblox and Twitter. Last but not least, there will be multiple opportunities to win some swag, so don’t miss the session.
