The following diagram shows the main components of a Cassandra with Portworx deployment running on top of Kubernetes: 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 A node is a worker machine in Kubernetes.. Learn More. Kubernetes provides only a limited understanding of database functionality. ... Thousands of applications rely on Apache Cassandra to store and retrieve this data, and DataStax Enterprise is the proven leader delivering the most reliability and performance. For example, cassandra-0: kubectl logs If your Cassandra nodes are not joining, delete your controller/statefulset then delete your Cassandra service: kubectl delete statefulset cassandra Datastax recently announced a Kubernetes operator for Cassandra with it’s of DSE 6.8 release. Since pods are mortal, the likelihood of failover events is higher than a traditionally hosted or fully managed database.

Connecting to a Cassandra cluster running within Kubernetes can range from trivial to complex, depending on where the client is running, latency requirements, and security requirements. It provides adjustable consistency guarantees, is horizontally scalable, is built to be fault-tolerant and provides very low latency, (sub-millisecond) writes. Most applications deployed on Kubernetes should be cloud-native and rely on external resources for their data and state. We are now running with Kong on Kubernetes backed by the power of Astra!
