Which consumer group should you assign a new employee with limited SQL skills to minimize the impact of their code execution on the ADW?

Assigning the new employee with limited SQL skills to the "Low" consumer group is a strategic move designed to minimize potential negative impacts on the Autonomous Data Warehouse (ADW).

The "Low" consumer group is configured to have resource constraints that limit the amount of compute and storage resources a user can consume. This is particularly beneficial in a collaborative environment where other users may also be executing queries and performing operations in the database. By placing the new employee in this group, you effectively safeguard against any poorly optimized or resource-intensive queries that could impede overall performance or disrupt the experience for more experienced users who might be running critical operations.

Moreover, this approach encourages learning and improvement over time. As the employee gains more SQL experience and understanding of best practices, they can be moved to a higher consumer group where they can operate with more resources and flexibility. Thus, starting in the "Low" group acts as a protective measure while allowing room for growth in their skills.
