Sebastian Schelter commented on MAHOUT-667:
-------------------------------------------

Constructors should be preserved, we could introduce new ones that take a 
PersistanceStrategy and provide a method getDefaultPersistanceStrategy() for 
the existing ones, similar to getDefaultCandidateItemsStrategy()

> Persistent storage of factorizations in SVDRecommender

> As discussed previously (https://issues.apache.org/jira/browse/MAHOUT-640) it 
> would be beneficial to provide a persistent storage mechanism for 
> factorizations created by SVDRecommender (in package 
> org.apache.mahout.cf.taste.impl.recommender.svd) as these can be time 
> consuming to produce. It would also allow factorizations to be computed on 
> one machine then distributed to other machines providing predictions, 
> improving efficiency and scalability.
> Having a "persistence strategy" interface has been suggested that could be 
> implemented as required. I'll try to post a outline proposal for discussion 
> purposes in the next few days but any comments or suggestions would be very 
> welcome.
