New options to manage proposition validity
Valid from Pega Version 7.2.1
Manage your decisioning strategy more effectively with proposition validity settings. You can now set your propositions as always active, inactive, or active only within a defined time period. Setting a validity period for your propositions helps you to plan your strategy and automatically activate or deactivate propositions in the future.
For more information, see Proposition validity.
Define adaptive model context
Valid from Pega Version 7.2.1
You can define model identifiers in the Adaptive Model rule instance, which serve as partitioning keys, by selecting properties from the top-level SR class of your application. The Adaptive Decision Manager (ADM) server uses model identifiers to create adaptive models that use the same configuration, but collect different adaptive statistics. Use model identifiers in the Adaptive Model rule to create adaptive models for your purposes.
For more information, see the Context tab on the Adaptive Model form.
DSM rulesets become part of the PegaRULES application
Valid from Pega Version 7.2.1
The Pega-DecisionArchitect, Pega-DecisionEngine, Pega-BigData, and Pega-NLP rulesets were moved from the PegaDM application record to the PegaRULES application record. This change makes decision management functionality available for Pega 7 Platform users by default without any additional configuration required.
For more information, see DSM rulesets become part of the PegaRULES application.
HDFS data sets support Parquet files
Valid from Pega Version 7.2.1
The Parquet file format has been added to the list of supported file formats for data storage in the Hadoop Distributed File System (HDFS) data set record. On the Pega 7 Platform, you can now access an HDFS data set that stores data in the Parquet file format and perform various operations on that data set.
For more information, see Big Data enhancements in decision management.
New rule type: External Data Flow
Valid from Pega Version 7.2.1
You can now create External Data Flow rules on the Pega 7 Platform. By using this rule type, you run predictive models outside of the Pega 7 Platform and directly in the external Hadoop data set infrastructure. Processing large amounts of data on an external infrastructure improves overall performance on the Pega 7 Platform by reducing data transfer between the Hadoop cluster and the platform.

New graphical framework for the Event Strategy rule form
Valid from Pega Version 7.2.1
The Event Strategy rule form introduces a new graphical framework that includes redesigned strategy shapes, improved navigation, and faster response time when building a strategy. These changes contribute to creating a more functional and engaging environment that allows strategy designers to successfully develop and maintain event strategy rules.
For more information, see Event Strategy rule type enhancements.
New shapes in the Event Strategy rule type
Valid from Pega Version 7.2.1
The Event Strategy rule type supports branching and merging of the data stream by using the new Split and Split and Join strategy shapes. You can now split your event strategy into several paths to identify multiple types of events with a single rule instance.
In addition, the Lookup shape replaces the Static Data shape. You can add static data anywhere in the strategy. For example, you can filter out irrelevant events, and then evoke static data for only the events that are relevant to the strategy.
For more information, see Event Strategy rule type enhancements.
State management support for data flows that run event strategies
Valid from Pega Version 7.2.1
You can now store the state of your data flow work items that contain event strategies in the Cassandra database of the decision data store. With this solution, you can recover the event strategy state without any loss of data. You can also pause and resume active data flows that invoke event strategies.
For more information, see Event Strategy rule type enhancements.
Extended proposition filter functionality
Valid from Pega Version 7.2.1
Multiple enhancements to the Proposition Filter rule type extend the functionality of proposition filters. When you configure the filter or the default behavior criteria in a proposition filter rule, you can select a strategy rule that contains an External Input shape. You can also apply the default behavior criteria to all incoming propositions that do not match the business issue or group defined in a proposition filter rule. Additionally, you can view the labels of when and strategy rules when you configure the filter or default behavior criteria.
For more information, see Proposition filter usability enhancements.
Import and export feature for generic decision data
Valid from Pega Version 7.2.1
New import and export functionality improves the management of generic decision data records (the records that do not belong to the Strategy Results class). You can now configure generic decision data records in a CSV file and later import that file to the Pega 7 Platform. You can also export the existing generic decision data record configuration from the Pega 7 Platform to a CSV file, and save that file in a directory that is external to the Pega 7 Platform.
