Performance enhancements to the Visual Business Director data set
Valid from Pega Version 7.3
When you create instances of the Visual Business Director data set, you can specify the granularity of data aggregations and select dimension levels to reduce the Visual Business Director memory footprint and query time. In addition, the Actuals Visual Business Director data set on the Data-pxStrategyResult class has been replaced with a regular Decision Data Store instance. You can now quickly update or synchronize records in the Actuals data set with the Interaction History data set.
For more information, see Data Set rule form - Completing Data Sets and Aggregation on the Visual Business Director data set.
Visual Business Director service renamed to Real Time Data Grid service
Valid from Pega Version 7.3
To avoid confusion in the Pega Marketing application, the Visual Business Director service has been renamed to Real Time Data Grid service.
For more information, see Real Time Data Grid service.
Improved adaptive model configuration and management
Valid from Pega Version 7.3
The usability of the Adaptive Model rule form has been improved by changes to the tabs and settings. Performance monitoring of Adaptive Model rules is now done through the new Decision Analytics workspace for business scientists. The Adaptive Models Management landing page has adapted to the new multinode architecture and displays the values for the number of outstanding responses and the time of the last update. Additionally, you can manually initiate updates from the Adaptive Models Management landing page.
For more information, see Changes to Adaptive Decision Manager.
Changes to Pega alerts that are related to Decision Data Store
Valid from Pega Version 7.3
The PEGA0085 alert informs users about insufficient disk space allocated for the Cassandra database. The PEGA0074 alert has been deprecated, and the PEGA0075 alert has been renamed and modified to include settings from the PEGA0074 alert.
For more information, see PEGA0074 alert, PEGA0075 alert, and PEGA0085 alert.
Improved diagnostics and logging for Decision Data Store nodes
Valid from Pega Version 7.3
On the Decision Data Store tab, you can view additional metrics from the Decision Data Store nodes that help with diagnosing Cassandra database problems. You can also set the logging level to control interactions from and to Decision Data Store nodes.
For more information, see Decision Data Service node status information and Configuring the Decision Data Store service.
Tracing Cassandra queries in a Decision Data Store data set
Valid from Pega Version 7.3
You can now enable the Trace option for every operation in the Decision Data Store data set to collect information about how the Decision Data Store queries are executed in Cassandra. You can view this information in the clipboard and use it to troubleshoot and optimize performance of the Decision Data Store data sets and Decision Data Store nodes. All the queries and related events are collected on the DDSTraces page on the same Pega thread.
For more information, see Tracing Decision Data Store operations.
Enhanced functionality of the Decision Manager portal
Valid from Pega Version 7.3
The Decision Manager portal now provides more revision management options. The Decision Analytics work area for development of predictive, adaptive, and text analytics models is now part of the Decision Manager portal. PegaUnit testing of rules is more convenient from a new Automated Testing landing page. Revision managers can reassign change requests back to strategy designers or other users of the Decision Manager portal without losing changes that were already made.
For more information, see Enhancements to the Decision Manager portal.
Use Kafka data sets in Pega Decision Strategy Manager
Valid from Pega Version 7.3
You can create Kafka data set rules to connect to an external Apache Kafka server cluster and use this data set in decision management for processing real-time streaming data. Integrating Kafka data sets into complex event processing (CEP) as part of Event Strategy rules provides a fault-tolerant and scalable solution for processing real-time data feeds.
For more information, see Kafka data sets in decision management.
Use definition classes to create Decision Data rules that contain text analytics records
Valid from Pega Version 7.3
Use the dedicated definition classes to create Decision Data rules that contain all the types of records that are used in text analytics, such as taxonomies, lexicon, entity extraction rules, and so on. By using these definition classes, you can quickly create, update, and manage the text analytics records in your application.
For more information, see Definition class of text analytics Decision Data rules.
Create resilient data flow runs
Valid from Pega Version 7.3
The resilience of data flow runs has been improved. If Data Flow service nodes fail, active data flow runs continue on the remaining functional nodes. Depending on the type of primary data source and the selected run failure policy, data partitions on the failed nodes can be reprocessed on another functional node or the data flow run is marked as failed for further investigation. You can also add or remove nodes from the Data Flow service while data flow runs are in progress. The runs are automatically rescaled.
For more information, see Data flow run updates.
