Hey HN! I built this GitHub Action that lets you create MySQL database branches in your CI/CD pipelines, similar to what Neon and PlanetScale offer.<p>What it does:<p>- Creates isolated MySQL environments for testing and development<p>- Lets you run schema migrations without touching production<p>- Can compare differences between source and branch databases<p>- Allows merging changes back to source when ready<p>- All automated within GitHub Actions<p>https://github.com/marketplace/actions/mysql-branch-action
