Modulus partiton
Posted: Tue Jan 29, 2008 4:42 pm
i am doing a join on input data from vitual dataset and an oracle table. The key is a single column of integer type. Right now i am hash partitioning and sorting both the inputs. Instead of Hash can i use Modulus. Developer guide says YES. But if i use modulus, does it ensure related records stay in same dataset. and which is fastest, hash or modulus. How the modulus work. does it also create any table like hash
