   @qinghui-xu @julienledem Leveraging the (protobuf) field ids is a great idea!
   
   @qinghui-xu, would you be so kind to rebase this PR, so we could give it a try on our platform?

> Field id is essential for some serialization framework such as protobuf, and they are used to keep schema forward/backward compatibility which could not be achieved by using field names. Currently field id is not persisted as file metadata.
