Batch Processing Strategies
The trade is latency for price, and the deciding constraint in these stems is nearly always whether somebody is waiting. A day of headroom is comfortably wider than batch turnaround; a feature with a person watching the spinner is the one case where the discount is unavailable. Partial recovery is the other half. A caller-chosen identifier on every item is what lets the failures be selected and resubmitted as a smaller batch, and the downstream effect has to be harmless when an item is processed twice, because a partial failure can leave the first half already applied.
