Understanding Kafka Streams

When envisioning a Kafka cluster, get started with the information being a river and waterfall. The water comes down and falls right into a lake (Kafka itself), and now you’ll do various things with it. Dig irrigation ditches to ship some knowledge off in numerous instructions.
