Customized application overview documents in App Studio

Valid from Pega Version 8.3

Keep stakeholders notified of the status of an application by customizing and generating an application overview document in App Studio. The overview may include information such as case types, roles, features in your application, and more. Select the chapters that you want to include in the overview, and then highlight the most relevant information by ordering the chapters. In addition to the application overview document, you can generate a detailed data model, either in Microsoft Word or Excel format.

Automatic retries for the SAVE operation on records

Valid from Pega Version 8.3

Batch and real-time data flow runs now automatically retry the SAVE operation on records when an error occurs because of resource unavailability. This functionality ensures that the records are eventually saved if the target data set is only temporarily unavailable, for example, because of load or network issues.

You can configure the default number of retries for the entire system in a dynamic system setting. To adjust the setting to different resource allocations and operating environments, you can update that number for each data flow run.

For more information, see Changing the number of retries for SAVE operations, Creating a batch run for data flows, and Creating a real-time run for data flows.

New send email automations and enhancements

Valid from Pega Version 8.3

You can now configure cases, flows, and activities to compose and send guardrail-compliant emails that conform to the MIME standard by using email automations. Use the new Call-Automation method to call an automation from an activity without writing Java.

You can also now categorize error messages in automations to quickly understand the type of error that occurred. In addition, page list data types are now supported for inputs and outputs in automations.

For more information, see Calling an automation from an activity and Viewing automations.

Cassandra 3.11.3 support for Pega Platform

Valid from Pega Version 8.3

Increase your system's reliability and reduce its memory footprint by upgrading the internal Cassandra database to version 3.11.3.

For on-premises Pega Platform™ users, after you upgrade to Pega 8.3, it is recommended that you manually upgrade to Cassandra 3.11.3. You can upgrade to Cassandra 3.11.3 on all operating systems except IBM AIX. If you do not want to upgrade to Cassandra 3.11.3, you can continue to use Cassandra 2.1.20, which is still supported.

For Pega Cloud Services 2.13 and later versions, Cassandra automatically upgrades to version 3.11.3 after your environment is upgraded to Pega Platform 8.3.

For information on how to manually upgrade to Cassandra 3.11.3, see the Pega Platform 8.3 Upgrade Guide for your server and database at Deploy Pega Platform.

Upgrade impact

After an on-premises Pega Platform upgrade, you still have the older version of Cassandra and must manually upgrade.

What steps are required to update the application to be compatible with this change?

To upgrade Cassandra, you must create a prconfig setting or a dynamic system setting with the new Cassandra version and then do a rolling restart of all the Decision Data Store nodes to upgrade them to the latest version of Cassandra.

 

REST API for monitoring DSM services

Valid from Pega Version 8.3

Decision Strategy Manager (DSM) now provides a REST API that you can use to monitor DSM services without having to access Pega Platform™. By integrating your daily monitoring tools with the management REST API, you can retrieve a list of DSM nodes, check the status of these nodes, and view details of a service from all nodes in the cluster.

For more information, see Getting started with Pega API for Pega Platform.

Create custom criteria for proposition filters by using the condition builder

Valid from Pega Version 8.3

Proposition filters now use the condition builder to define the criteria that a proposition or group of propositions must match in order to be offered to a customer. The condition builder provides a simple, flexible tool for selecting and grouping the entry criteria.

For more information, see Create custom criteria for Proposition Filter rules with the condition builder (8.3).

More efficient navigation between applications in App Studio

Valid from Pega Version 8.3

The new My Applications gadget helps you switch applications in App Studio more conveniently. You can also search applications by name instead of choosing an application from the list, and then select the access role that you want to use. In addition, you can see descriptions of your applications and create an application by going to the My Applications landing page. To use the My Applications gadget, ensure that you update the UI Kit to version 14.

For more information, see Adding the My Applications gadgetSwitching between applications in App Studio.

Fast-track change requests for high-priority business needs

Valid from Pega Version 8.3

Perform urgent rule updates through fast-track change requests. The new type of change requests supports addressing high-priority business needs and deploying them immediately, without the need to disrupt an ongoing revision.

For more information, see Release urgent business rule updates through fast track change requests (8.3) and Creating application overlays.

Support for custom database tables in external Cassandra clusters

Valid from Pega Version 8.3

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 Integrating Cassandra with your application.

Text analytics models editing and versioning

Valid from Pega Version 8.3

Pega Platform™ now supports editing and updating training data for text analytics models.

Pega Platform also supports the versioning of text analytics models. When you update the model, Prediction Studio creates an updated model version. You can then switch between the model versions.

Upgrade impact

In versions of Pega Platform earlier than 8.3, the training data for text models was stored in the database. In Pega Platform version 8.3 and later, the training data for text models is stored in Pega Repository. You cannot build new models without setting the repository. After the repository is set, all text models are automatically upgraded and will work normally.

What steps are required to update the application to be compatible with this change?

After a successful upgrade, set the repository in Prediction Studio before building or updating any Natural Language Processing (NLP) models.  In Prediction Studio, click Settings > Text Model Data Repository.
