I am reading a bunch of files from cloud storage using TextIO.Read and the data is all in the same format (CSV). I need to de-dupe the records by ID and keep only the latest one, but I cannot tell which one is the latest by only the row data, instead it is implied by the filename.
Any way I can get access to the filename when using TextIO? If not, any suggestions on a workaround? thanks! --Cory
