Overview
Based on Data Pipelines Pocket Reference (Densmore) and Fundamentals of Data Engineering (Reis & Housley). An ETL runbook is the operational contract for a data job: how to monitor it, diagnose when it breaks, and recover data integrity. Densmore's standard: data pipelines fail in subtle ways - not always with an error, sometimes with silent data loss or incorrect rows. A good runbook covers job failures AND data quality failures.
The test: can an on-call engineer who didn't build this pipeline detect a problem, isolate the cause, and restore data integrity at 3am?
