Introducing DB Branching in mirrord: Run Against a Shared Environment With a Personal, Isolated Database

mirrord introduces DB Branching, a feature that creates temporary, isolated database branches for testing schema changes and migrations safely. When enabled, it automatically overrides database connection strings to point to a separate branch that mirrors the main database, allowing developers to test changes without affecting shared staging environments. The feature currently supports MySQL databases and is available in mirrord for Teams, with a step-by-step guide demonstrating how to test schema changes using a Go service on Kubernetes.
