Which essential function is performed automatically by Oracle Autonomous Data Warehouse?

Oracle Autonomous Data Warehouse performs automatic provisioning of services, which means it can allocate and manage the necessary resources for data warehousing operations without requiring manual intervention. This automatic provisioning enhances operational efficiency and ensures that resources are utilized effectively according to the demands of the workload.

This capability allows users to focus on analyzing data rather than managing infrastructure, as the system independently adjusts capacity and performance based on current usage patterns. Automatic provisioning also facilitates scalability, enabling the warehouse to grow and adapt seamlessly with changing data requirements.

In contrast, manual tuning of workloads, daily intervention for maintenance, and quarterly evaluations imply a level of manual oversight and involvement, which goes against the autonomous nature of the system. The essence of Oracle Autonomous Data Warehouse is to minimize human oversight and intervention in resource management, making automatic provisioning a critical feature.
