Scylla Operator

Scylla Operator is a Kubernetes Operator for managing and automating tasks related to managing a Scylla clusters.

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.

Quickstart

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.
• EKS: An advanced guide for deploying Scylla with the best performance settings on Amazon Elastic Kubernetes Service.

You can also use Helm charts to deploy both Scylla Operator and Scylla clusters:

# Stable charts
helm repo add scylla-operator https://storage.googleapis.com/scylla-operator-charts/stable

# Latest charts
helm repo add scylla-operator https://storage.googleapis.com/scylla-operator-charts/latest
