Using a data page with a predefined key enhances performance by leveraging the caching mechanism of Pega. When a data page is loaded with a specific key, it is stored in memory. Subsequent accesses to the data page with the same key do not require fetching the data again from the external data source, significantly reducing the access time. This approach is particularly beneficial in cloud deployments where network latency can impact performance. It ensures that once the data for a particular customer is fetched and stored in the cache, accessing the same customer's information again is much faster, addressing the performance issue reported.References: Pega Community documentation on data pages and performance best practices.

When two teams work on different enhancements within the same ruleset and wish to keep their work separate, the best practice is to create a new ruleset version for one of the teams and to use branch rulesets for each team. This allows for parallel development without interference, and the teams can merge their work back into the main ruleset when they're ready. References: Pega best practices for parallel development.

For offline support, it's necessary to have the access groups configured to allow offline access to users so that the correct rules and data can be synchronized to the user's device. In addition, the case types must be configured to function properly in an offline environment, ensuring that users can create, update, and submit cases without a network connection.
