Creating CSV files via MySQL - Any limits imposed?

Question

I am going to be creating some CSV files via MySQL with code like the below for example..

SELECT id, name, email INTO OUTFILE '/tmp/result.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
ESCAPED BY ‘\\’
LINES TERMINATED BY '\n'
FROM users WHERE 1

But I was just wondering if the resulting file is going to be rather large (possibly several GB's) is there things I should be concerned about or precautions I should take? Like memory problems etc?
