You disable stuff that slows down processing and then import the data using the SQL engine's own LOAD DATA commands. Not that slow either. Really though, you first have to ensure your documents all match a standard, since a lot of people just expect csv, tsv and other documents to all be the same, and they are not. So you have to do extra work anyway. Might as well use SQL too.
