Problem
A working pipeline silently becomes expensive and nobody notices until the invoice.
Solution
Instrument, attribute, then guard. 1. unit metric per pipeline ($ per run, per 1M rows) 2. baseline the last N runs 3. fail CI on regression > threshold 4. hard caps (warehouse resource monitors, quota limits) Alert on the *unit* metric, never on total spend, so healthy growth doesn't page anyone and a regression does.
When not to use
- Negligible fixed-cost workloads
Security scan
Last sweep 2026-10-24: 0 finding(s), 0 marked as examples.
Context
Any cloud data platform with variable compute.
Forces
- Spend varies with data growth
- Regressions hide in growth
- Engineers need fast feedback
Tradeoffs
| Choose this when | Costs & caveats |
|---|---|
| cheap early detection, no invoice surprises | needs metrics plumbing and a baseline to be maintained |
