Sean Owen updated MAHOUT-977:
-----------------------------
Resolution: Fixed
Fix Version/s: 0.7
Status: Resolved (was: Patch Available)
Looks good, I'm going to commit this much since it's in good working order and
solves a need. I do think it's a bit copy-and-paste of the superclass and I
wonder, is the superclass needed? It seems like a special case of the subclass
now.

> This is a suggested improvement to PlusAnonymousUserDataModel.
> Currently the ID of the anonymous user is fixed to Long.MIN_VALUE. Only one
> set
> of temp data can be inserted into the model and used at one time.
> I propose the change to enable multiple users to insert into this
> model concurrently in a thread-safe manner.
> The idea is to define a pool of available anonymous user IDs. Every
> time a new anonymous user makes a request, the next available
> TEMP_USER_ID is pulled from the queue. After recommendations are
> retrieved, the TEMP_USER_ID can be returned to the pool.
