Schema Evolution and Compatibility Modes
Learn how Avro schemas evolve over time and how Schema Registry compatibility modes let producers and consumers change independently without breaking each other.
Why Schemas Change
Real systems evolve: new fields are added, old ones deprecated. Schema evolution is the discipline of changing schemas without breaking existing producers or consumers.
The Compatibility Contract
Schema Registry enforces a compatibility mode on each subject. Before registering a new schema version, the registry checks it against existing versions and rejects breaking changes.
