Problem

The data platform team is comparing throughput overhead across pipeline states. Calculate the average absolute difference between rows in and rows out for successful pipelines and for running pipelines separately, then return the absolute gap between those two averages as a single value. Treat 'success' case-insensitively (so 'success' and 'Success' both count).

Summary

Production overhead versus staging.
