Overview: A guided workshop for Kafka Streams
What is Kafka Streams?
Kafka Streams is a client library that enables developers to create streaming applications, using Java or Scala, that produce data to and consume data from Kafka clusters. Kafka Streams combines the simplicity of writing and deploying standard Java and Scala applications on the client side with the benefits of Kafka's server-side cluster technology.
The Kafka Streams library provides a domain-specific language (DSL) for creatinge pipelines to process data streams scalably with minimal code. The DSL supports stateless operations such as filtering an existing topic to create a new topic that contains messages matching specific criteria. Stateful operations are also possible, such as producing aggregates and joining messages from multiple input streams (topics).
