I am using for project now the procedure Fastknn.

i can choose as method=APPROXIMATE | EXACT.

 

But the documentation doesn't describe which method it use. like as in proc distance. so my question is which distance method is Fastknn is using.

 

exampple: 

Euclidean distance, Squared Euclidean distance, shape distance, chebychev

P.S. Proc Fastknn is incredible fast.  the procedure create for me a dataset of 159 billion rows with the distnance and make the decision of which is the nearest in only 900 seconds.
