Configuring the Decision Data Store service

Store decision management data in a Cassandra database and manage the Cassandra cluster by configuring the Decision Data Store (DDS) service.

Examples of decision management data include customer data, decision results, and input data for adaptive and predictive models.

Note: This procedure applies only to on-premises deployments.

Procedure

Configure the Decision Data Store (DDS) service by specifying where you want to store decision management data:

To store decision management data in an internal Cassandra database, see Configuring an internal Cassandra database.
Select this option if you want to use the default Cassandra database for Pega Platform. In this model, the nodes (machine environments) that are designated to hosting the Decision Data Store have their Cassandra Java Virtual machine (JVM) started and stopped for them, by the JVM that is hosting the Pega Platform instance.
To store decision management data in an external Cassandra database, see Connecting to an external Cassandra database.
Select this option if you are already using Cassandra within your IT infrastructure, and want the solutions you build with Pega Platform to conform to this architecture and operational management.
