Data Engineering Associate with Databricks Practice Exam

What can be set up to notify the data engineering team if the ELT job has not been executed for over an hour?

1. An hourly status report.

2. An error notification for failed jobs.

3. An alert for the query that checks job execution time.

4. A weekly performance summary.

The correct answer is: An alert for the query that checks job execution time.

Setting up an alert for the query that checks job execution time is the most effective approach for notifying the data engineering team if the ELT job has not been executed for over an hour. By using a specific query that monitors the execution status and timings of the jobs, the data engineering team can receive real-time notifications regarding any delays in the execution process. This proactive monitoring allows for immediate investigation and resolution of potential issues, ensuring that the data pipeline remains functional and efficient. This response is particularly tailored to ensure that the team is alerted in a timely manner, making it a more responsive solution compared to options like an hourly status report or a weekly performance summary, both of which provide retrospective insights rather than immediate alerts. While error notifications for failed jobs are essential for handling issues after they occur, they do not address scenarios where jobs may not fail but simply do not execute within the expected timeframe. The focus on job execution time alerts enables a more preventative approach to data pipeline operations.
