zhavir opened a new issue #12949:
URL: https://github.com/apache/pulsar/issues/12949


   **Is your enhancement request related to a problem? Please describe.**
   I was wondering if there was a possibility to use protobuf in order to auto-generate code for my pulsar client services (both producer and consumer). By reading documentation and searching on the internet I was able to find some references related to other languages (like Java or C). 
   
   **Describe the solution you'd like**
   I've tried to do something like that, obviously without success.
   ```
   import _pulsar
   from pulsar import Client
   from pulsar.schema import Schema
   
   from generated_schema.test_pb2 import TodoList
   
   
   class ProtobufSchema(Schema):
       def __init__(self, record_cls):
           super(ProtobufSchema,
                 self).__init__(record_cls, _pulsar.SchemaType.PROTOBUF, <IdontKnwoHowToGetTheSchema>,
                                'PROTOBUF')
   
       def encode(self, obj):
           self._validate_object_type(obj)
           return obj.SerializeToString()
   
       def decode(self, data):
           return self._record_cls.FromString(data)
   
   
   def test():
       client = Client('pulsar://localhost:6650')
       producer = client.create_producer(topic='persistent://cloudacademy/accounts/sso-configuration-updated.v1',
                                         schema=ProtobufSchema(TodoList))
   
       producer.send(TodoList(owner_id=1, owner_name='test'))
   ```
   
   
   **Additional context**
   For a reference, I'm expecting something like the integration with Avro, but instead with Protobuf (with autogenerated classes)
