The crypto application is a multifaceted example that extends the Deephaven Community Core docker images.
The publisher connects directly to a number of cryptocurrency exchanges via the XChange library, and publishes quotes and trades into a Redpanda Kafka server.
The Deephaven server consumes the Kafka feed, and creates a number of useful tables from the cryptocurrency quotes and trades.
The web server packages up a specific layout for the cryptocurrency tables.
The client is a stand-alone client that demonstrates pulling the table data from Deephaven into a remote application.
- docker or docker-compatible engine
- docker-compose
To launch the latest release, you can clone the repository and run via:
git clone https://github.com/deephaven-examples/crypto-application.git
cd crypto-application
docker-compose up -d
Or, you may download the release docker-compose.yml file if preferred:
mkdir crypto-application
cd crypto-application
curl https://github.com/raw/deephaven-examples/crypto-application/main/release/docker-compose.yml -o docker-compose.yml
docker-compose up -d
This will launch the web server at http://localhost:10042/ide/.
The stand-alone client is not started by default. To see it in action, run:
docker-compose up client
This will connect to the server and print out the real-time BTC/USD prices once a second for ten seconds, then exit.
The default configuration creates a few named volumes. If you want to delete just the containers, run:
docker-compose down
If you want to delete the containers and the volumes, run:
docker-compose down -v
- Java version between 8 and 16 is required to build. See Gradle Compatibility Matrix.
- docker or docker-compatible engine.
./gradlew clean build

To develop against an unreleased version of the Deephaven core images, change the base images as appropriate in gradle.properties.
To change the defaults, edit the environment file.
