Chapter 4. Technology preview

Case modeler in Business Central now includes the new process designer. It provides the option to model a case as a sequence of stages so it is simple to define a case model at high-level. Case modeling supports three types of tasks: human tasks, sub-processes, and sub-cases.

Process instance migration is now available as a standalone service that contains a user interface and a back end, and packaged as a Thorntail uber JAR. The process instance migration service enables you to define the migration between two different process definitions, known as a migration plan. You can apply the migration plan to the running process instances in a specific Process Server.

For more information about the process instance migration standalone service, see the Process Instance Migration Service page in GitHub.

You can use the Prediction Service API to provide a prediction service that assists with human tasks. The prediction service can use AI. For example, you can use Predictive Model Markup Language (PMML) models or Statistical Machine Intelligence and Learning Engine (SMILE) to implement the service.

Configuration of Business Central for high availability on premise is currently a Technology Preview feature. Note that high-availability deployment of Business Central is now supported on Red Hat OpenShift Container Platform version 3.11.

You can use the Constraint Streams API as an alternative to the Drools Rules Language (DRL) to program incremental score calculations in plain Java. The Constraint Streams API is fast, scalable, and debuggable. You can use any IDE to develop and debug solvers using the Constraint Streams API. It uses deltas that enable the engine to redo only necessary calculations. It also supports justifications, so you can review the reason a solution was reached in order to debug the solver. Note that the Constraint Streams API fully supports the NQueens, Task assigning, and Flight Crew Scheduling use cases.

An installer wizard is provided in the OpenShift operator for Red Hat Process Automation Manager. You can use the wizard to deploy a Red Hat Process Automation Manager environment on Red Hat OpenShift Container Platform with the Operator.

Red Hat JBoss Data Grid replaces Elasticsearch as the distributed highly scalable full-text search and analytics engine for Red Hat Process Automation Manager.

Red Hat Data Grid is built from the Infinispan open-source software project and contains indexing capabilities that enable you to store, search, and analyze high volumes of data quickly and in near-real time. In a Red Hat Process Automation Manager clustered environment, it enables you to perform complex and efficient searches across cluster nodes.
