how to use hortonworks schema registry w/ PROTOBUF?

[洁徐]

it is mentioned:

Features	Registry	Confluent Schema Registry
REST API for Schema Management	Yes	Yes
Supported Schema Types	AVRO (0.3), PROTOBUF, JSON, extensible...	AVRO only

Any suggestion on how to enjoy that?

[洁徐]

it sounds currently only

Apache Avro is included (https://github.com/hortonworks/registry/blob/2570a10c580401505b7fcca7387ef7fe3e02aac1/NOTICE.txt)

any tip or notice while on using it with protobuf?

Hi,

      Hortonworks SchemaRegistry allows one to define their own type which could be other formats like Protobuf , Json or some proprietary data format. This can be doable by defining the type and building the respective SerDes using the interfaces provided.  We currently built functionality around Avro and will add Protobuf support soon.

Thanks,

Harsha

Thank you harash

it seems some interfaces are avro-specific, like registry/schema-registry/serdes/src/main/java/com/hortonworks/registries/schemaregistry/serdes/avro/AvroSerDesHandler.java, so I am still a little confused

would you pls, if feasible, highlight  me w/ a list of interfaces and class for me to implement and extend for protobuf?

Thanks,

Jie

Hi Jie,

You can implement protobuf implementation and register that via config like below.

 

• Implement SchemaProvider like the way it is done for avro with AvroSchemaProvider
• Implement snapshot serializer/deserializer APIs as similar to avro serializer and deserializer.
• Configure that as one of the schema providers in registry.yaml as shown here

 

Pl let us know if you need any clarifications in implementing the above.

 

Thanks,

Satish.

Hi Jie,

You may want to raise Github issue for this task.

 

Thanks,

Satish.
