Hi, It might be a naive question but I was concerned as I am trying to read from a file. My question is if I have a file with n lines and i want m lines out of that where n << m, would the first operator process only the first m lines or would it go through the entire file?
If it does go through the entire file, is there a better way to just get the top m lines using readCsvFile function? Thanks & Regards Biplob Biswas
