Apache Cassandra is a highly scalable, distributed NoSQL database built for write-heavy workloads, horizontal scaling, and tunable consistency, with no single point of failure. K8ssandra is an open-source operator that automates Cassandra provisioning, scaling, backups, and repairs on Kubernetes. This guide deploys a multi-node Cassandra cluster via the K8ssandra Operator, with cert-manager, persistent block storage, and a LoadBalancer service for external access.
Prerequisites: a Kubernetes cluster with at least 4 nodes / 4GB RAM each, a workstation with kubectl and helm configured against the cluster.
Install cqlsh
cqlsh is the Python-based CLI for querying Cassandra.
