To improve performance when fetching data from an external source in a cloud-deployed application, you should configure the data page to use a predefined key. This approach allows the data to be loaded once and then accessed quickly for subsequent requests.

Understanding Data Pages in Pega:Data pages in Pega are used to cache data, so it doesn't have to be retrieved from the source every time it is needed. Using a predefined key means that the data page is loaded with specific data that can be reused.

Configuring Data Pages with Predefined Keys:

Step 1: Define a data page and configure it to use a key for accessing data.

Step 2: Ensure the data page is set to load on demand or at a specific point in the process.

Step 3: Once the data is loaded with the predefined key, subsequent accesses to this data page will be faster because the data is already available in the cache.

Advantages of Using Predefined Keys:This approach reduces the need to repeatedly fetch data from the external source, thereby improving performance and reducing network latency issues in cloud environments.

References:Pega Documentation on Data Pages and best practices for caching and data retrieval provides detailed steps and examples on how to configure data pages with predefined keys for optimized performance.

To isolate database-related performance issues:

Investigate when the database is used most heavily (B): Understanding peak usage times can help pinpoint when the database is under the most strain. This information is crucial for identifying potential bottlenecks and optimizing performance.

Lower query-time-related alert thresholds (C): By lowering the alert thresholds for query times, you can capture more detailed information about slow-running queries, helping to identify and address inefficient database operations.

Summarize Function with Filter Condition After Aggregation:

Using a report with a summarize function on Quantity and a filter condition applied after aggregation ensures that the report accurately displays categories with more than 5 items ordered.

References:

Pega documentation on report definitions and aggregation functions outlines how to apply filters after summarizing data to meet reporting requirements.

Therefore, the correct answer is:

C. A report with a summarize function on Quantity and filter condition Sum (Quantity) > 5 that the system applies after aggregation.
