This application is a Spring Boot based webservice that provides a REST API to save and query times driven in Mario Kart 8 Deluxe Time Trials.
This service uses Kafka to consume new times and to publish new records when the record for a track is broken.
A MongoDB database is being used to store the data.
This application is set up to be run with Docker. The Dockerfile will start the service by running
the services jar. Therefore, the jar has to be created first by running mvn package.
In order to test the application in a full dev environment, Docker Compose can be used. The full
environment is defined in compose.yaml and can be started by running docker compose up.
This project features a Swagger/ OpenAPI documentation.
It is available through the Swagger-UI at /swagger-ui/index.html.
