Unlocking Pega's Hidden Potential: Undocumented Features & Best Practices (Pega Infinity ‘23 & Pega Infinity ‘24 Edition)

With Pega Infinity ‘23 and Pega Infinity ‘24 rolling out, many developers are still exploring new capabilities. While the official documentation covers major updates, I’ve discovered some lesser-known features and best practices that can significantly enhance your development workflow. Let’s dive in! 🚀

🔹 1. Constellation UI: Hidden Performance Boosters

Pega Infinity ‘23+ promotes Constellation UI, but many developers face challenges with performance tuning. Here are two hidden optimizations:

✅ Use Optimized Data Pages in Constellation

• Unlike traditional UI, Constellation prefers Optimized Data Pages over clipboard-heavy approaches.

• Avoid referencing pyWorkPage directly—use a JSON-based API-driven approach instead.

✅ Leverage Client-Side Caching

• Define cache configurations in the DX API settings to reduce API calls for repetitive UI interactions.

  
  
  
  

🔹 2. API-First Development: Lightweight Data Retrieval

Pega Infinity ‘23 introduced improved DX APIs, but did you know you can create custom lightweight APIs without exposing entire case data?

💡 Use Case:

• Instead of fetching the entire case, create a custom API response using Data Transforms in Service REST rules.

• This reduces payload size and speeds up UI loading times.

  
  
  
  

🔹 3. Managing Process Fabric: Best Practices

Process Fabric allows multiple Pega applications to work together. However, some hidden tricks can improve its efficiency:

✅ Use Cross-App Assignments Effectively

• When using Federated Case Management, enable auto-resolve settings for smoother workflow transitions.

✅ Monitor Fabric Hub Performance

• Use PDC (Pega Predictive Diagnostic Cloud) to track case routing efficiency in a multi-app setup.

  
  
  
  

🔹 4. Undocumented Clipboard Pages in Pega Infinity ‘23/Pega Infinity ‘24

Some Clipboard pages have changed! Here are new or updated hidden pages:

🔸 pxInteractionHistory – Stores real-time AI decisions (useful for Next-Best-Action insights).

🔸 pxFabricAssignments – Tracks case movement across multiple applications.

🔸 pxDataPageRequestInfo – Helps debug complex Data Page calls in Constellation UI.

🔹 5. Custom Performance Alerts for API Calls

In Pega Pega Infinity ‘24, performance logging for APIs has improved. You can:

✅ Enable Custom Alerts

• Go to Decision Data Store (DDS) logs and set alerts for slow API responses.

• Use pxRequestor.pxElapsedTime to track long-running REST service calls.
