> Using Field directly doesn't yet answer the question "how to interpret given field". I agree -- but at least it makes it possible to get the info > So we gonna have a helper function that takes a Field and returns... "the type object" representing the type of that field -- either arrow DataType or extension. If the goal is to have implementation of extension types in the core of datafusion, I agree with this statement and that is an excellent point. However, in my mind the goal is actually to have almost no specific extension type support in DataFusion itself, but instead have all the implementations live elsewhere (e.g. all geospatial packages live in some other repo, and there is no geospatial knowledge in the core of DataFusion) -- This is an automated message from the Apache Git Service.
