Airflow hello DAG

2 parts

First DAG, retries, sensors, and when not to use Airflow.

Start with part 1 →

1. 1 Airflow hello: your first DAG as a ticket rail Orchestration is a ticket rail, not a junk drawer. Learn what an Airflow DAG is, how tasks and dependencies map to real runbook stations, and how to sketch a first daily orders rail you can actually operate.
2. 2 Airflow hello: retries, sensors, and when not to use it Retries buy time for flukes; sensors encode waiting with deadlines. Learn when to retry, how to sensor a late file without burning workers, and when Airflow is the wrong tool for the job.
