# Camel-Kafka-connector FHIR Source Example

## Introduction

This is an example for  Camel-Kafka-connector

## What is needed

- A Kafka Cluster running

## Running Kafka

```
$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties
$KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties
$KAFKA_HOME/bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic patients
```


## Setting up the needed bits and running the example

You'll need to setup the plugin.path property in your kafka

Open the `$KAFKA_HOME/config/connect-standalone.properties`

and set the `plugin.path` property to your choosen location

In this example we'll use `/home/ldemasi/connectors/`

```
> mkdir -p /home/ldemasi/connectors/ && cd /home/ldemasi/connectors/
> wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-fhir-kafka-connector/0.10.1/camel-fhir-kafka-connector-0.10.1-package.tar.gz
> untar.gz camel-fhir-kafka-connector-0.10.1-package.tar.gz
```

Now you can run the example

```
$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties source/CamelFhirSourceConnector.properties
```

Just connect to your Kafka and check with the kafka console consumer that the messages are available in the kafka topic.
```bash
$KAFKA_HOME/bin/kafka-console-consumer.sh --bootstrap-server kafka:9092 --topic mytopic --from-beginning
