If you're using custom sql it's recommanded to use extracts if you can.
I should be able to do that for this project, thanks. If that weren't an option, what would be the better choice?

I think that it depends on your database. Because Tableau will just issu an sql statment and the databse will do all the work.
So you must check for that the excecution plan for your query and optimise it depending on the result.
