Maximum transactions a user needs before becoming a mentor

The following setting specifies the maximum number of transactions a user can have before becoming a mentor. The sifter uses this setting if the Purchase or Clickstream Engine is using that mentor set. We can specify the value as one of the following:

• A percentage of the total number of items in the database.

  For example:

  <mentor_set_name>.max_mentor_xactions = 75%
  

• The maximum number of transactions that is, without a percentage).

  For example:

  <mentor_set_name>.max_mentor_xactions = 18
  

Use the following guidelines for setting <mentor_set_name>.max_mentor_transactions

Total Number of Items in Database	Suggested Setting
< 1000	<= 100
1000–5000	<=500
5000–10,000	<= 1500
10,000+	<= 1500

For more information on how the sifter makes use of <mentor_set_name>.max_mentor_xactions, see Guidelines for configurable recommendation dynamics.
