Quarkus-with-Kafka Project

This project uses Quarkus, the Supersonic Subatomic Java Framework.

Using Docker

Before you running this application run in your terminal the command to up the docker images.

docker-compose up -d

Into docker-compose.yaml file has what do you need to use this application, like:

  • Kafka
  • Zookeeper
  • Kafdrop
  • Mongodb

Apache Kafka is a popular open-source distributed event streaming platform. It is used commonly for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications. Similar to a message queue, or an enterprise messaging platform

Zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services

Kafdrop is a web UI for viewing Kafka topics and browsing consumer groups. The tool displays information such as brokers, topics, partitions, consumers, and lets you view messages.

Mongodb is a document database with the scalability and flexibility that you want with the querying and indexing that you need

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.type=uber-jar

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Pnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/code-with-quarkus-1.0.0-SNAPSHOT-runner
