Query the Application, Not a Database: “Interactive Queries” in Kafka’s Streams API

Kafka Summit SF 2017 | Streams Track

Kafka Streams allows to build scalable streaming apps without a cluster. This “Cluster-to-go” approach is extended by a “DB-to-go” feature: Interactive Queries allows to directly query app internal state, eliminating the need for an external DB to access this data. This avoids redundantly stored data and DB update latency, and simplifies the overall architecture, e.g., for micro-services.
