Scylla Operator

Kubernetes Operator for Scylla (Beta version :warning:)

Scylla is a close-to-the-hardware rewrite of Cassandra in C++. It features a shared nothing architecture that enables true linear scaling and major hardware optimizations that achieve ultra-low latencies and extreme throughput. It is a drop-in replacement for Cassandra and uses the same interfaces.


To quickly deploy a Scylla cluster, choose one of the following options:

  • Generic: Follow this guide for the general way to use the operator.
  • GKE: An advanced guide for deploying Scylla with the best performance settings on Google Kubernetes Engine.


Scylla Operator is in Beta status.

The scylla-operator is a Kubernetes Operator for managing Scylla clusters. Currently it supports: * Deploying multi-zone clusters * Scaling up or adding new racks * Scaling down * Monitoring with Prometheus and Grafana

Future additions include: * Integration with Scylla Manager * Version Upgrade * Backup * Restore

Top-Performance Setup

Scylla performs the best when it has fast disks and direct access to the CPU. To deploy Scylla with maximum performance, follow the guide for your environment: * GKE


If you find a bug or need help running scylla, you can reach out in the following ways: * #kubernetes channel on Slack. * File an issue describing the problem and how to reproduce.

Building the project

You can easily build Scylla Operator in your environment: * Open the Makefile and change the IMG environment variable to a repository you have access to. * Run make publish and wait for the image to be built and uploaded in your repo.
