Example code for connecting to a Apache Kafka cluster and authenticate with SSL_SASL and SCRAM.

To easily test this code you can create a free Apacha Kafka instance at https://www.cloudkarafka.com

Running locally

If you just want to test it out.

Configure

All of the authentication settings can be found in the Details page for your CloudKarafka instance.

export CLOUDKARAFKA_BROKERS=broker1:9094,broker2:9094,broker3:9094
export CLOUDKARAFKA_USERNAME=<username>
export CLOUDKARAFKA_PASSWORD=<password>

Run

git clone 
cd java-kafka-example
mvn clean compile assembly:single
java -jar target/kafka-1.0-SNAPSHOT-jar-with-dependencies.jar

This will start a Java application that pushes messages to Kafka in one Thread and read messages in the main Thread. The output you will see in the terminal is the messages received in the consumer.
