Hi Sebastian, Let me get your use case right, You cant to do a pair counting like a join. you might need to use PIG or something similar to do this easily. Mahout's PFPGrowth counts the co-occurring, frequent n-items not just co-occurrence of two items. There you just need either one of the viewed or bought transaction table to generate these patterns.
