Introducing the schemadiff command line tool
3 min read
PlanetScale released the schemadiff command line tool, a wrapper around Vitess's schemadiff library. The tool validates, normalizes, and diffs MySQL schemas from standard input, files, or a live database. It supports three-way merge logic and migration concurrency ordering for zero-downtime schema changes.
