[GitHub] [beam] damccorm opened a new issue, #21066: Protobuf schema provider row functions break on camel-case field names

[GitBox <gi...@apache.org>]

damccorm opened a new issue, #21066:
URL: https://github.com/apache/beam/issues/21066

   ProtoByteBuddyUtils.protoGetterName() _depends_ on field names being snake-case. But the Protobuf style guide only _recommends_ that field names are so defined.  
   
   Snake-case is not enforced by protoc and my team have always created proto field names in camel-case (perhaps we didn't understand that protoc would automatically rewrite field names for us). It is likely that we are not alone.
   
   If one calls a row function against a proto instance whose field were defined in camel-case, an IllegalArgumentException results from the ProtoByteBuddyUtils snake-case assumption.
   ```
   
   SerializableFunction myRowFunction = new ProtoMessageSchema().toRowFunction(new TypeDescriptor<MyDataModel.ProtoPayload>()
   {});
   MyDataModel.ProtoPayload payload = …
   Row row = (Row) myRowFunction.apply(payload);
   
   
   ```
