In this tutorial, the Pods that belong to the StatefulSet are Cassandra nodes and are members of the Cassandra cluster (called a ring).When those Pods run in your Kubernetes cluster, the Kubernetes control plane schedules those Pods onto Kubernetes Nodes. With Cassandra on Kubernetes, enterprises and users will have a consistent scale-out stack for compute and data. The benefits of a Kubernetes operator for Cassandra are: Zero downtime Operations with cass-operator K8ssandra delegates core Cassandra management to the DataStax Kubernetes Operator for Apache Cassandra, cass-operator .
