The Apache Avro Schema Evolution Agent manages schema lifecycle for event-driven architectures by interfacing with the Confluent Schema Registry REST API. It validates schema changes against compatibility rules (backward, forward, full, and transitive variants) before registration, preventing breaking changes in production Kafka topics. The agent parses Avro IDL and JSON schema formats, detects field additions, removals, type promotions, and default value requirements. It generates migration code for schema transitions, handles union type evolution, and manages subject naming strategies for topic-key and topic-value schemas. The agent supports schema references for complex nested types, provides diff visualization between schema versions, and integrates with CI pipelines to enforce compatibility gates. Includes automatic documentation generation showing schema lineage and consumer impact analysis.
