A quick demonstration of ScyllaDB with configurable read/write throughput

ScyllaDB Quickstart Demo

This is a quick start demonstration of ScyllaDB with Docker.

To run the demo for yourself. First start a single node cluster with the following command:

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

Wait 60s or so for the node to start. Tip: you can view ScyllaDB logs with:

docker logs -f node1

Next, run the demonstration application which will simulate artificial load from an Internet of Things app, measuring sensor data from millions of unique devices:

docker run --rm --link node1:node1 \
    --publish 8000:8000 \
    --env DATABASE_URL=node1:9042 \
    --env ROCKET_ADDRESS=0.0.0.0 \
    --name demo timkoopmans/scylladb-quickstart

The demo application will now be running on port 8000. You can access the application by visiting http://localhost:8000/index.html.

Note: the demo will simulate high load with simulated reads and writes, so you can expect to see the demo app consuming a lot of CPU. You can stop the demo at any time with:

docker stop demo

By default, the app will simulate high volume load with a 20:80 read:write ratio. If you would like to experiment with different ratios, pass them in as command line arguments to the demo application. For example, to simulate a 50:50 ratio:

docker run --rm --link node1:node1 \
    --publish 8000:8000 \
    --env DATABASE_URL=node1:9042 \
    --env ROCKET_ADDRESS=0.0.0.0 \
    --name demo timkoopmans/scylladb-quickstart 50 50

Once you're happy with the demo, you can stop all the containers with:

docker stop node1 demo
