-- Returns a 'DataSource' that includes metadata and data file information, as well as the current status of the 'DataSource'.
--
-- 'GetDataSource' provides results in normal or verbose format. The verbose format adds the schema description and the list of files pointed to by the DataSource to the normal format.
