This is a minimum POC of using protobuf with Kafka.
first bring up the docker images by using
docker-compose -f all.yml up
next, simply run it
sbt run
There will be a bunch junk printed out on console and you should see a text: I GOT IT, and followed by an object printed twice.
NOTE: if you are running Mac, update all the hard-coded IP to match your local docker IP.
