Well thats the implementation detail of the system, there are various strategies, driven by various aspects of the product. Not generic like the algorithms in Mahout. I dont think its something Mahout should handle anyway.
It will be great if Foursquare folks on the list can share stories/issues/bugs or even patches they made in getting Mahout jobs to run. Should help us polish Mahout for a v1.0 milestone.
