Kafka implementation

Sending message(bytes) and header of message type to kafka topic from service and then consumed same topic bytes and special headers with defining type of payload and converting to special object of this type and process it with service methods

(Commonly this payload type using for heartbeats sending and main object payload, but this project just example of usages of some technologies. Correctly using different publishers, different topics and different listeners for better application designing)

REST implementation

You can ask me why in this project every rest request invocation goes firstly to kafka and then handling this request with kafka message handler and process it with service. I can answer... just because I can, and want to show how kafka can work
