3 questions in Batch Orchestration.

Quiz

A data platform's batch jobs have complex interdependencies and a failure early in the night cascades. What orchestration properties matter?

On the last Sunday in October a UK data platform's 01:30 daily job ran twice and duplicated rows in a revenue table. On the last Sunday in March the same job did not run at all. The scheduler is configured in local time. What failed, and what is the structural fix?

The batch orchestrator's scheduler process dies at 02:40 with about 30 tasks already running on workers. It is restarted at 03:00. The nightly load includes a MERGE into a revenue table and a push to a payments vendor. What happens between 02:40 and 03:15?
