Published Release Notes

Control group configuration for predictions

You can now configure a control group for your predictions in Prediction Studio. Based on the control group, Prediction Studio calculates a lift score for each prediction that you can later use to monitor the success rate of your predictions.

For more information, see Customizing predictions.

Easy access to proposition-related rules when creating change requests in revision management

When selecting propositions for change requests in Decision Strategy Manager, you can view the proposition filter, strategy, and when rules that are associated with the decision data the selected propositions belong to. In addition, you can include those rules in change requests. To view and add any associated rules to a change request, the rules must be part of the application overlay. With the ability to view and select all proposition-related data, you can consistently revise not only propositions themselves but also all associated rules.

For more information, see Proposition-centric revision management functionality.

Updates to the Event Strategy rule

When you design event strategies, you can use the Filter shape for basic arithmetic and text expressions. You can also specify start conditions for the tumbling and sliding windows.

Decisioning services now use default node classification

Decisioning services have been integrated with default node classification on Pega^® Platform to provide a unified way of creating and initializing services. As a result of the integration, the Data Flow service has been divided into Batch and Real Time services to better handle different types of data flow runs. You can now specify separate subsets of Data Flow nodes for batch data flow runs and real-time data flow runs to divide the workload between these two subsets.

For more information, see Node classification, Data Flows landing page, and Services landing page.

Enable business users to own parts of an enterprise application

Decision Manager functionality allows business users to own parts of an enterprise application within the boundaries defined by IT. PegaDM includes the Pega-DecisionManager ruleset that supports this functionality.

System architects define the boundaries for business users in the Decision Manager portal using revision management and proposition authorization facilities in Designer Studio. Access control is provided through custom roles, which system architects can create based on granular privileges. The Decision Manager portal provides business users with a controlled environment for the workflow, and the activities necessary to address the objectives of a revision.

Aggregate data in interaction history summaries

You can now group, aggregate, and filter interaction history data in a single strategy component. By using interaction history summaries, you can create refined data sets that simplify strategy frameworks and accelerate decision-making. Aggregated data sets are easier to process, manage, and troubleshoot.

For more information, see Data Sources landing page

Data flow life cycle monitoring

You can now generate a report from the Run details section of a Data Flow rule that provides information about run events. The report includes reasons for specific events which you can analyze to troubleshoot and debug issues more quickly. You can export the report and share it with others, such as Global Customer Support.

For more information about accessing event details, see Creating a real-time run for data flows and Creating a batch run for data flows.

Improved reliability of Visual Business Director

Improvements to the reliability of Visual Business Director (VBD) eliminate the impact of temporary access loss to the VBD cluster. The improvements include the ability to continue writing data to a VBD dataset while the corresponding server node is unavailable, enhancements to single-case data flows that write data to VBD, and a reduction in the VBD cache size.

For more information, see Eliminate the impact of temporary access loss to the VBD cluster (8.4).

Improvements to Visual Business Director (VBD)

Business monitoring and reporting no longer depends on the external Visual Business Director service because VBD is now embedded in the Pega 7 Platform. You add a VBD node to the cluster to access VBD for simulations and monitoring. In addition, when you use the Google Chrome browser, VBD launches as a new HTML client that provides the visualization.

For more information, see The Visual Business Director (VBD) HTML client and Accessing Visual Business Director (VBD).

Support for custom database tables in external Cassandra clusters

Pega Platform™ now supports a connection to external Cassandra clusters through a dedicated Database Table data set, which reduces the need for data ingestion and export. You can use custom tables that you store in your external Cassandra cluster in data flows for accessing and saving data. You can access your custom data model by mapping the model to a Pega Platform class.

For more information, see Connecting to an external Cassandra database through a Database Table data set.
