[All Certified Data Engineer Associate Questions]

A Delta Live Table pipeline includes two datasets defined using STREAMING LIVE TABLE. Three datasets are defined against Delta Lake table sources using LIVE TABLE.

The table is configured to run in Production mode using the Continuous Pipeline Mode.

What is the expected outcome after clicking Start to update the pipeline assuming previously unprocessed data exists and all definitions are valid?

  • A. All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist to allow for additional testing.
  • B. All datasets will be updated once and the pipeline will shut down. The compute resources will persist to allow for additional testing.
  • C. All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will be deployed for the update and terminated when the pipeline is stopped.
  • D. All datasets will be updated once and the pipeline will shut down. The compute resources will be terminated.

Selected Answer: C
Continuous Pipeline Mode in Production mode implies that the pipeline continuously processes incoming data updates at set intervals, ensuring the datasets are kept up-to-date as new data arrives. Since the pipeline is set to Continuous Pipeline Mode, it will keep running and updating the datasets until it is manually shut down. The compute resources are allocated dynamically to process and update the datasets as needed, and they will be terminated when the pipeline is stopped or shut down. This mode allows for real-time or near-real-time updates to the datasets from the streaming/live tables, ensuring that the data remains current and reflects the changes occurring in the data sources.
