A Primer on Kafka Streams

Bill Bejeck has an introduction to Kafka Streams:

Kafka Streams is an abstraction over Apache Kafka® producers and consumers that lets you forget about low-level details and focus on processing your Kafka data. You could of course write your own code to process your data using the vanilla Kafka clients, but the Kafka Streams equivalent will have far fewer lines, because it’s declarative rather than imperative. As a library, Kafka Streams lets you create a standalone application that can be run anywhere that can connect to a Kafka broker, whether that’s a laptop or a hefty cloud server. You just need to provide it with the host and port name of a broker. Combining Kafka Streams with Confluent Cloud grants you even more processing power with very little code investment.
