Hello and welcome to a QMP playground

0. Put `127.0.0.1 core-kafka` in your hosts file. Trust me.

1. Start the local kafka stack
   bash ./kafka-stack/start.sh
   1

2. Produce/Consume with Go
   go run ./golang-producer-consumer/main.go
   You're now producing/consuming 1 message per second to the topic "my-topic-1" in group "gogroup". See the program output for controls and options.

3. Produce/Consume with Java
   cd java-producer-consumer ; bash ./build.sh ; bash ./one_consumer.sh
   cd java-producer-consumer ; bash ./build.sh ; bash ./one_producer.sh
   You're now either producing or consuming 1 message per second to the "my-topic-1" topic and "javagroup" group. Ctrl-C will escape. I don't get paid enough to know Java too.

4. View Stats

5. bash ./kafka-stack/start.sh
   2

BONUS
   To run your own programs with this kafka-stack, do
      . ./kafka-stack/start.sh
   and choose
      3
   Your shell now has the environment variables it needs to use the Go qmp client with this stack.
