Subject Re: CachingRecommender versus Recommender
Date Tue, 15 May 2012 16:35:15 GMT
Recommender is the interface that all implementations implement.
CachingRecommender wraps any other instance of Recommender and
transparently caches its responses.

You would use this in a case where you have memory to spare and want to
save CPU by not recomputing recs per user frequently.

This helps only to the extent that your caller would frequently rerequest
recs from one user.
