This repository is related with the article: [Kafka Streams with Quarkus](https://piotrminkowski.com/2021/11/24/kafka-streams-with-quarkus/).

It shows how to build a simple stock market application that consumes Kafka Streams.

The following picture illustrates our architecture:




## Run locally

### Usage

You need to have Maven, JDK11+ and Docker (or Testcontainers Cloud Agent) installed on your local machine.

First, run the `order-service`:

```shell

cd order-service

mvn quarkus:dev

```

It will automatically start Kafka using Redpanda (Kafka API compatible platform). \

Then, run the `stock-service`:

```shell

cd stock-service

mvn quarkus:dev

```

Observe the logs. \

You can access Quarkus Dev UI console: `http://localhost:8080/q/dev`. \

You can also call some REST endpoints with analytical data:

```shell

$ curl http://localhost:8080/transactions/products

$ curl http://localhost:8080/transactions/products/3

$ curl http://localhost:8080/transactions/products/5

```
