Scylla Operator

Kubernetes Operator for Scylla (Pre-release version ⚠️)

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:

  • Minikube: super quick and easy way to get started with the Scylla operator.
  • GKE: advanced guide for deploying Scylla with the best performance settings.
  • Generic: your platform isn't included? Follow this guide!


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:

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:


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.
