title: Best approach loading a text file (.txt) to bigquery table
body: <p>Anyone got any pratical idea with regard to what is the best possible approach to upload a text file to a bigquery table? I have a few  zipped text files I need to download from a remote SFTP server and load it into a bigquery table. Should I download it to a google cloud storage and upload it from there to bigquery for faster speed? The text files are about 5GB each and will grow further.
  Thank you.</p>
