I know before I asked about vertical scaling. You cleared it @Erick Ramirez. But we are changing it manually, as per our requirements. Is there any option like where it scales automatically, when needs more memory.

If you are referring to the Vertical Pod Autoscaler (VPA), then you should be able to use it. cass-operator does not have any built-in support for it, but I do not think any special support is required as the VPA works directly with pods.
The Horizontal Pod Autoscaler (HPA) does support custom resources. A resource can have a scale subresource that is used by HPA. cass-operator does not have any integration with HPA.
Scaling a Cassandra cluster can be a very expensive operation due to the data streaming involved, so I would exercise caution about auto scaling the cluster with HPA.
If you're referring to the cass-operator and question #6395, the operator does not support it. It will only provision statefulsets based on the configuration you've given it.
Let me know if I misunderstood your question. I'd be happy to edit my answer. Cheers!
