Kafka Streams is a client library for building applications and microservices, where the input and output data are stored in a Kafka cluster. It 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.
- Quick Start Guide
- The Kafka Streams Quick Start demonstrates how to run your first Java application that uses the Kafka Streams library by showcasing a simple end-to-end data pipeline powered by Kafka.
