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 improve performance during synchronization for users of an offline-enabled mobile app, it's crucial to manage the data pages that are synchronized. Declaring large data pages in the data page whitelist ensures that only necessary data is preloaded and cached on the device, reducing the amount of data transferred during synchronization and thus improving performance.

For modeling different types of vehicles in an insurance quote application:

Separate Data Types:

Create a distinct data type for each vehicle type (e.g., Car, Motorcycle, Truck). This allows for specific properties and business logic for each vehicle type.

Single Vehicle Page List:

Maintain a single page list property in the quote case type to hold vehicle details.

At runtime, dynamically identify the page class for each entry in the list based on the type of vehicle being processed. This approach allows for flexibility and maintainability.
