Subject Re: Deploying a massively scalable recommender system with Apache Mahout
Date Thu, 04 Aug 2011 08:14:08 GMT
David, can you please give us some details about your usecase?

It seems like you're trying to reimplement the system I described in

That system is highly optimized for a certain class of usecases and only 
makes sense if you have like 100+ million datapoints and 100+ 
requests/second to your recommender.

If you just want to start diving into recommendation mining and build a 
first system to play with, working with this article is definitely the 
wrong approach. In that case, I highly suggest you get a copy of "Mahout 
in Action", which gives a superb introduction 
to recommendation mining with mahout.
