PREVIEW: “Interactive Queries” in Kafka’s Streams API

on YouTube ↗06m

" summary

Preview demonstrates that Kafka Streams exposes Interactive Queries so applications directly query local state stores instead of an external database, implementing a DB-to-go pattern that removes redundant storage and DB update latency. It uses Kafka Streams’ stateful processing primitives—aggregations, joins and windowed state—runs as ordinary Java consumer-group apps, and keeps state durable and distributed via Kafka so queries are low-latency and the architecture stays scalable and fault-tolerant.
