This is a port of the Vert.x in Action 10k steps challenge application to Quarkus.
Some code parts have been ported to Quarkus APIs (e.g., the Kafka code uses Quarkus Messaging APIs rather than the Vert.x Kafka client) while other parts take advantage of Vert.x clients and APIs running in Quarkus.
This project is not just a good showcase of reactive Quarkus: it also shows how to take advantage of the Vert.x ecosystem in Quarkus.
You will need:
- We recommend Java 21+
- Native compilation works with a GraalVM distribution such as Mandrel
- You will need to run containers: Podman Desktop is your friend
We also recommend:
You can run each individual service in Quarkus "dev" mode.
Pick the directory name, and use just as in:
just congrats-service
There is a simple activity generator that you can run with:
just run-native-generator
Edit the activity-generator/generator.json file to customize the workload.
You can compile all services to native executables in native-apps/:
just native-build
Note: this will take several minutes.
Before running the services you will need a PostgreSQL database and Apache Kafka. Podman can create a Pod for you:
just create-demo-pod
and you can clean this Pod and its associated containers with:
just delete-demo-pod
Running each service individually can be tedious and will require many tabs.
You can instead use hivemind to start then all at once:
just run-all-native
