How many unique idenfiiers do you have?
If they are large (in terms of bytes) but you don't have that many of them
(eg the total possible number you'll ever have is < INT_MAX), you could
store them as factors. You get the speed of integers but the labeling of
full "precision" strings. Factors are fast...

I have to be very carefull when releasing the data. If a user just use
read.csv functions, they by default cast the
