Configuring an internal Cassandra database
Version:
Start storing data in an internal Cassandra database by creating a Cassandra cluster and configuring the Decision Data Store (DDS) service.
For more information about the internal Cassandra deployment, see Cassandra overview.
-
Create a Cassandra cluster by assigning the DDS node type to at least three Pega Platform nodes.
To increase the volume of data and the volume of interactions that you process, assign the DDS node type to a higher number of nodes. For more information, see Sizing a Cassandra cluster.For more information, see Assigning node types to nodes for on-premises environments.
