A pipeline without alerting is a pipeline that fails silently. Downstream consumers — dashboards, models, business reports — depend on pipelines completing successfully and on time, with no visibility into pipeline internals. When a pipeline fails at 2am and nobody is alerted, the team discovers the problem when a business stakeholder reports wrong numbers at 9am. Effective alerting catches failures at the moment they occur, routes them to the right person with enough diagnostic context, and distinguishes between urgent failures and informational events that can wait for business hours.
Alert fatigue is the failure mode of over-alerting: when every pipeline failure, retry, and warning generates a page, engineers learn to ignore alerts and the truly critical ones are missed. Every alert should be actionable — if the correct response is 'wait and see', it should not be an alert. Every alert should be routed to the right person — the engineer who owns the failing pipeline, not a shared inbox that everyone monitors and nobody acts on. These two criteria eliminate the majority of low-value alerts.

🏏 Think of it like cricket: Migrating from Airflow to Prefect is like the same bowling coach shifting from traditional Test cricket notation to a modern T20 analytics dashboard — the underlying ball-by-ball data (the business logic) is exactly the same. What changes is how the data is recorded, displayed, and acted upon. The yorker that Bumrah bowls in over 20 is identical whether it is recorded in the old scorebook (Airflow DAG file) or the new analytics platform (Prefect flow). The migration is a transcription exercise, not a strategy change — and a wise coach verifies that the runs, wickets, and economies match exactly between the old and new system before decommissioning the scorebook. That verification step is the whole heart of the migration: because the yorker is unchanged, the only honest test is to run the same over through both systems and confirm the recorded runs, wickets and economies match to the last digit before the old scorebook is thrown away. Rushing to burn the scorebook the moment the shiny dashboard lights up is how teams lose a season of records to a silent transcription slip. The coach keeps both systems running in parallel for a while, reconciles their outputs ball by ball, and only when every figure agrees does he trust the new dashboard alone — a transcription is only complete when you have proven nothing was lost in the copying.
