Hi [~davidzchen],

I think that it is sufficient to support only flat schema right now. Of course, we have a plan to expand our schema and physical operators to support nested data model, but not now. Also, you can skip PROTOBUF data type because currently it is only used in intermediate data.

Since you use only your own time, it may be hard to proceed this work faster. I understand. I think that if you share your progress or create some subtasks, some of us can collaborate this work with you.

Best regards,
Hyunsik Choi
