checking on Pega Platform Support Guide (Updated to 8.8 version), i see that for kubernetes installation we must specify an external cassandra server, but cassandra server is used for decision engine in CDH, if our customer doesn't use CDH can we avoid to specify cassandra server?
Hi, Usage of Cassandra is not mandatory, if not CDH. In the values.yaml file, you can comment the Cassandra settings before application deployment. If cassandra server, No idea where to make changes to disable its purpose.
If you are not using Customer Decision Hub, you can avoid specifying a Cassandra server by setting 'cassandra.enabled' to false in the values.yaml file. Comment out or remove the DDS connection settings as well. No changes are needed on the Cassandra server itself since it won't be used in this scenario.
