🚀 Quick Setup Guide for ScyllaDB

ScyllaDB is a high-performance NoSQL database compatible with Apache Cassandra. It’s ideal for applications that demand low latency and high throughput. This guide walks you through a quick setup of ScyllaDB using Docker for simplicity.

🧰 Prerequisites

Before you begin, ensure you have the following installed:

⚙️ Step-by-Step Setup Using Docker

1. Pull the ScyllaDB Docker Image

docker pull scylladb/scylla

2. Run a ScyllaDB Container

Start a single-node Scylla instance:

docker run --name scylla-node1 -d scylladb/scylla

For more control (e.g., data persistence or exposing ports):

docker run --name scylla-node1 \
  -d --restart unless-stopped \
  -p 9042:9042 -p 10000:10000 \
  -v scylla-data:/var/lib/scylla \
  scylladb/scylla

3. Verify the Container is Running

docker ps

You should see scylla-node1 running.

🧪 Connecting to ScyllaDB

You can use cqlsh to interact with ScyllaDB:

Option 1: Use cqlsh from a Python container

docker run -it --rm --network host \
  nuvo/docker-cqlsh:latest --cqlversion=3.4.5 \
  <host-ip> 9042

Replace <host-ip> with your Docker host IP (usually localhost on Linux).

Option 2: Install cqlsh locally (via Cassandra tools)

Install Apache Cassandra tools, then run:

cqlsh localhost 9042

📄 Example CQL Commands

Once connected via cqlsh, try the following:

CREATE KEYSPACE demo WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};

USE demo;

CREATE TABLE users (
  id UUID PRIMARY KEY,
  name text,
  email text
);

INSERT INTO users (id, name, email) VALUES (uuid(), 'Alice', 'alice@example.com');

SELECT * FROM users;

🛑 Stopping and Cleaning Up

To stop and remove the container:

docker stop scylla-node1
docker rm scylla-node1

To remove the volume:

docker volume rm scylla-data
