Per inviare a un singolo file utilizzare parallel off
unload ('select * from venue')
to 's3://mybucket/tickit/unload/venue_' credentials
'aws_access_key_id=<access-key-id>;aws_secret_access_key=<secret-access-key>'
parallel off;
Inoltre consiglio di usare Gzip, per rendere quel file ancora più piccolo per il download.
