NEW QUESTION 28
While Autonomous Transaction Processing and Autonomous Data Warehouse use the same Oracle database, which statement is true about the workloads?
- A. Data that is bulk loaded, by default, uses the row format in Autonomous Transaction Processing where Autonomous Data Warehouse data format is columnar.
- B. Autonomous Transaction Processing workloads are optimized for data warehouse, data mart, and data lake.
- C. Autonomous Data Warehouse workloads are optimized for mixed workloads.
- D. Autonomous Transaction Processing memory usage optimizes workloads for parallel joins and aggregations.
Answer: A
Explanation:
- Both ADW and ATP share the Autonomous Database platform of Oracle Database on Exadata Cloud infrastructure.
The difference is how the services have been optimized within the database. When you start loading data into the autonomous database, we store the data in the appropriate format for the workload.
* If it is ADW, then we store data in columnar format because that's the best format for analytics processing.
* If it is ATP, then we store the data in row format because that's the best format for fast single row lookups.
- Oracle Autonomous Database is offered in two workload-optimized flavors
* Autonomous Data Warehouse (ADW), which has been optimized for analytic workloads
* Autonomous Transaction Processing (ATP). ATP is optimized for transaction processing or mixed workload
