Does esist a data structure that is able to store something like 480189 keys with efficient memory usage?
What is the range of your keys - do they use the full 32-bit of Int - and what type are the values?
From Netflix Prize documentation: CustomerIDs range from 1 to 2649429, with gaps. There are 480189 users. The values are UArr (Word32 :*: Word 8), from uvector package. Thanks Manlio
