description Apache Kafka Streams Overview
Kafka Streams is a powerful client library for building applications and microservices where the input and output data are stored in Kafka clusters. Unlike Flink or Spark, it is not a separate cluster-based engine; it runs as a standard Java application, making it incredibly lightweight and easy to deploy within existing microservice architectures. It provides high-level DSLs for transformations, aggregations, and joins, as well as low-level Processor APIs.
It is the ideal choice for developers who want to perform stream processing without the overhead of managing a separate distributed processing cluster.
