David Arthur commented on MAHOUT-202:
-------------------------------------
In a full-fledged recommender system, you usually want good ad-hoc access to
your ratings data (for UI or whatever). This would afford that, and might be
useful if someone used HBase as their primary data store.
Also, considering a end-to-end application, if it takes ~1s to gather the
user's neighborhood of ratings, and then some amount of time to do the
calculation (probably a few ms), that's still not bad for ad-hoc, scalable,
always-up-to-date, (albeit simple) recommendations. I guess this would be a
situation where you lose some performance in exchange for scalability.
Like I said before, if people think it would be useful - great. If not, no big
deal.
