Kafka Streams je knjižnica za stream processing — gradnjo aplikacij, ki v realnem času obdelujejo in transformirajo podatke v Kafka temah (filtriranje, transformiranje, agregiranje, povezovanje tokov). Omogoča obdelavo podatkov v realnem času neposredno na Kafki.
Kaj je stream processing
STREAM PROCESSING → process data CONTINUOUSLY as it arrives (in real time), vs batch
(processing stored data periodically):
→ consume events from topics, transform/analyze them, produce results (often to other topics)
→ real-time: react to and process events as they happen (low latency)
→ for: real-time analytics, transformations, monitoring, enrichment, aggregations
