Which Cloud Composer feature should a Data Engineer use to define a recurring DAG that runs nightly at 02:00 IST and depends on the prior day's run completing?
AA DAG with schedule_interval = '0 2 * * *' and depends_on_past = True (or wait_for_downstream)
BCloud Memorystore
CCloud DNS
DManual scripts kicked off by a developer at 2am
Answer & Solution
Correct answer: A. A DAG with schedule_interval = '0 2 * * *' and depends_on_past = True (or wait_for_downstream)
Composer's schedule_interval + depends_on_past handle recurring + dependent DAGs (per PDE §5.2 + §2.3). The others aren't DAG scheduling.
