Engines to be used for mentor tables to be rebuilt

After the sifter finds mentors for users, it writes the user's mentor assignment to a mentor table (Lps_User_Mentor). It also keeps the current list of unique mentors in a mentor pool table (Lps_Mentor_Pool).

In order to build the mentor table, the sifter requires the Recommendation engines to provide a similarity value for two users. To determine this similarity, the Preference Engine uses ratings data and the Clickstream Engine uses clickstream data. The engines are configured to use a particular mentor set and rating or transaction set.

The following setting specifies the engines for which mentor tables need to be rebuilt. Only mentor tables of the specified engines will be updated. If you are using a single mentor table for more than one instance of the Clickstream or Preference Engine, specify only one engine.

db.applic.sifter.source = <engine1>, <engine2>

For example:

db.applic.sifter.source = MoviePref, MovieActivity
