Published Release Notes

Decision Strategy Manager

Fixes were made that improve the configuration and execution of Batch Decisions. In particular,  the capability to use Structured Data has been enhanced. Some notable improvements have also been made to the UI of Visual Business Director.

• The structured data input configuration will now work even though there is no data.
• VBD has been enhanced to work with Version 7.1.
• The structured data input configuration will now work with nested structures.
• Association rules from Version 6.3 will now work with 7.1 structured data.

Expose properties in Decision Data Store

You can now expose properties in Cassandra-based Decision Data Store data sets. With this solution, you can update single properties in extended customer analytic records (XCAR) without having to update the full customer record.

For more information, see XCAR in Decision Data Store.

Enhancements to bulk editing options for unversioned propositions

Bulk editing options for unversioned propositions have been enhanced to allow the use of Excel for editing. You can export and import unversioned propositions into Excel by using the Import wizard. Additionally, data types replace decision tables as the new storage format for unversioned propositions.

For more information, see Data type management and Proposition management enhancements.

Reuse existing propositions across applications

You can reuse existing propositions from built-on applications by using a new wizard to copy proposition groups across applications. This wizard gives you more options and flexibility when you define the business hierarchy in your application.

For more information, see Proposition management enhancements.

Migrate DDS data across various schema versions

You can use multiple versions of a single Decision Data Store (DDS) data set type in different applications that run on the same Pega^® Platform instance and efficiently move data across those versions even if the underlying data schema is different. This solution improves the data management process and simplifies the reuse of existing data.

For more information, see Decision Data Store migration.

Support for PMML version 4.3 in predictive models

You can now leverage predictive models in the Predictive Model Markup Language (PMML) version 4.3 by importing them into predictive models on Pega^® Platform. Pega Platform utilizes a large part of the PMML standard with the exception of some PMML 4.3 features that are not supported in the Predictive Model rule.

For more information, see Support for PMML version 4.3 in predictive models and Creating a predictive model.

Emit remaining event strategy data at the end of a data flow run

Data flows have been updated to prevent data loss in event strategies. By default, when a batch or a real-time data flow stops and it contains an event strategy with Tumbling windows, all of the events that are in the Tumbling windows are emitted. Event emission triggers further processing in the event strategy, like aggregations and joins.

For more information, see Enhancements to data flows that contain event strategies and Event Strategy rule form - Completing the Event Strategy tab.

New aggregation functions in event strategies

You can use new functions in event strategies to build standard and complex aggregations. With new aggregation functions you can detect additional patterns in streams of data and deliver actionable insights.

For more information, see Adding aggregations in event strategies.

Continue batch data flow runs that failed and reprocess partitions with the failed records

You can now continue batch data flow runs that failed and complete them with failures. You can also identify all the records that failed during a batch data flow run that is completed with failures. After you fix all the issues that are related to the failed records, you can reprocess the failures by resubmitting the partitions that contain the failed records. This option saves time when your data flow run processes millions of records and you do not want to start the run from the beginning.

For more information, see Data flow run updates.

Decision Data Store and HDFS data set types become resumable

Decision Data Store (DDS) and HDFS data set have been enhanced to be resumable. As a result, data flow runs that reference Decision Data Store or HDFS data sets as their primary data source are now resumable. You can pause and resume such data flow runs.

For more information, see the Resumability of data flow runs section in Data flow run updates.
