[FOLLOW UP QUESTION TO #6379]
okay. What I want to know actually, there is a field called "size", where it indicates number of nodes. It is a way of horizontal scaling. Is there any way for vertical scaling (increase of CPU/memory).

To add to Saravanan's answer, you need to edit the configuration of your cluster using the kubectl edit command. For example:
$ kubectl -n cass-operator edit cassdc dc1
You will need to reconfigure the resources allocated to the nodes. Here is an example allocation in the cassandra-3.11.6/example-cassdc-full.yaml YAML on GitHub:
resources:
requests:
memory: 24Gi
cpu: 6000m
limits:
memory: 24Gi
cpu: 6000m
When you save the configuration, the cass-operator will apply the changes and perform a rolling restart. Cheers!
Please see the Resources section in the cass-operator yaml
You have the ability to control how much cpu and memory you can allot to each pod. In our case each pod is like a node.
