Un-split brain MySQL

Ike Walker, Database Architect at GitHub, will discuss "Un-split brain MySQL".

Is there a way to amend a MySQL split brain scenario? When two servers are diverged from each other, is it possible to identify and undo the conflicting changes?

We introduce gh-mysql-rewind, which combines multiple technologies to achieve auto-resolution of data divergence. This presentation explains how gh-mysql-rewind works, and how it is being tested in production to validate its operation.
