This code is the companion of the blog post Kafka as a coordinator
This project uses Docker to create a cluster of 3 microservices that consume from a Kafka topic using the Kafka Streams API.
The main processing function is here.
Docker should be installed.
To run:
docker-compose up -d --build && docker-compose logs -f our-service our-service2 our-service3
Once the environment has been started, you have to add some commands with:
curl --data "device=key1&lat=2&lon=5" -X POST http://localhost:3004/device-point
curl --data "device=key1&lat=2&lon=6" -X POST http://localhost:3004/device-point
To get rid of all:
docker-compose down --rmi all --remove-orphans
docker image rm pandeiro/lein:2.5.2 wurstmeister/kafka:2.11-2.0.0
