問題文
A retailer wants a message sent to an operations queue whenever the number of out-of-stock views for a product crosses a threshold within a short window. Which combination delivers that?
選択肢
- A calculated insight and a report subscription, since the report can be scheduled to reach the operations queue as soon as the recomputed figure exceeds the threshold that the retailer defined.
- A data graph refresh.
- Publishing a membership is how any external system is notified of a condition being met, so a segment on the shortest schedule and an activation to the operations platform are enough.
- A streaming insight that detects the condition, paired with a data action that fires when it is met.
