Event Schema Versioning Basics

Evolve events safely

Event schema versioning adds fields compatibly, uses registries and validation, keeps producers/consumers in sync, and deprecates fields with timelines to avoid breaking pipelines.

Stay Compatible

Additive changes preferred; avoid breaking removals.

Register and Validate

Use schema registry; validate at produce/consume time.

Migrate

Deprecate fields with timelines; monitor consumer readiness.
