Schema Evolution Basics

Change schemas safely

Schema evolution uses additive changes, defaults, and versioning to allow old/new producers/consumers to coexist without breaking.

Additive First

Add fields with defaults; avoid breaking removals.

Version and Validate

Track schema versions and validate producers/consumers.

Migrate Gradually

Deploy in phases; clean up deprecated fields later.
