BigQuery Python Client v0.28.0: Can't recover {Dataset,Table}References from Dataset or Table objects #4327
Description
Hello,
In v0.28.0 of the BigQuery Python Client, it doesn't seem possible to recover the original DatasetReference or TableReference used to create the the Dataset or Table, thus preventing any part of the API (or a user's application) that requires a reference to also take the Dataset or Table object. It seems the reference used in creating the Dataset or Table is lost on object creation [1][2].
For example, in the client.load_table_from_file() function [3], a table_ref is expected; it seems logically unreasonable that a full Table object can't be used to fulfil the need for a table reference.
Cheers,
Rob
