Accumulator
Use the accumulator utility if we are using the Item Affinity Engine. This utility accumulates the number of times every possible item-to-item combination occurs.
Similar to the sifter for the other LikeMinds engines, the accumulator runs in the background processing item event data. It writes this data to the table specified by the <item_affinity_set>.item_affinity.output.table setting. The accumulator is installed as part of the PZN_Utilities.ear. It is run through the LikeMinds scheduling mechanism (see Scheduling LikeMinds Events).
