Schema Registry 为 Avro 和 Protobuf 等内置编码格式维护 Schema 文本，但对于自定义编解码 (3rd-party) 格式，如需要 Schema，Schema 文本需由编解码服务自己维护。 Schema Registry 为每个 Schema 创建一个 Schema ID，Schema API 提供了通过 Schema ID 的添加、查询和删除操作。 Schema Registry integration Schema Inference¶.

To maintain maximum flexibility though, we’ve implemented both code artefacts for the main languages and a centralised repository for dynamic access. Protobuf and Schema Registry. Protocol buffer schemas are represented with what are called descriptors, and descriptors themselves can be serialized as protocol buffers so that you can save them on Up to this point, the Protobuf schema has been controlled by the producer application that uses the io.confluent.kafka.serializers.protobuf.KafkaProtobufSerializer serializer to register the schema with the managed Schema Registry while the records are being serialized. Although this is handy for demos and proofs of concept, the schema will Avro semantics are quite different to that of Protobuf, as it is typically used with a schema definition provided in a header to a file.

Schema Registry supports multiple formats at the same time. For example, you can have Avro schemas in one subject and Protobuf schemas in another. Furthermore, both Protobuf and JSON Schema have their own compatibility rules, so you can have your Protobuf schemas evolve in a backward or forward compatible manner, just as with Avro. 2020-11-05 2018-10-17 2019-12-17 Confluent 5.5.0 understands not just Avro schemas, but also json-schema and protobuf.
