# sarama-example

Start kafka with:

```bash

docker-compose --project-name=sarama-example up

```

Open 3 new terminal windows and run the following in each:

```

KAFKA_CONSUMER_ADDRESS=localhost:9092 KAFKA_PRODUCER_ADDRESS=localhost:9092 go run main.go

```

Every 20 seconds, each instance of the app will publish 5 messages.

You should see that only 1 of the apps will be receiving any messages.

Even stopping the runner that is receiving the messages to cause a rebalance just pushes all messages to one of the other consumers.

Run the following to clean up kafka

```

docker-compose --project-name=sarama-example down

docker-compose --project-name=sarama-example rm

```
