One path for training and serving

Difficulty 2 of 5

The fraud model was trained on order counts from the order database. Since the online view restarted at 0:10, the counts it serves no longer match. Keep mismatched lookups below 3,000 and value age below 10 s. You can make 3 edits.

0:24. Served order counts differ from the training table. Mismatched lookups pass 3,000.
