Exam DBDEA Topics: jobs Difficulty: hard

A Lakeflow Job declares a job-level parameter target_date, and one of its notebook tasks declares a task parameter with the same key target_date but a different default. An on-call engineer then triggers the job with Run now, passing their own value for target_date. Which value does that task receive?

Options (Reading Mode) Click to filter discussion →
  1. A. The task parameter's default, because task-level settings are always the most specific
  2. B. The job parameter's default, because job-level settings override everything including Run now
  3. C. An error at run time: declaring the same parameter key at two levels is rejected by the platform
  4. D. The Run now value wins; below that, the job-level parameter beats the task parameter on a shared key
Reveal answer

Correct answer: The Run now value wins; below that, the job-level parameter beats the task parameter on a shared key
