Kafka, Flink and WarpStream—explained through a squirrel chase

The Great Apple Run is an illustrated introduction to real-time data streaming. Five dogs use a fictional “Bark Line” to follow squirrels moving apples across a backyard wall.

Apache Kafka: the Bark Line

Apache Kafka becomes a durable line of event records. The dogs can react to new messages as they arrive or replay earlier records later, much like applications reading from Kafka topics.

Apache Flink: context while events are moving

Apache Flink enriches the moving records with time, place, direction and identity. Instead of seeing only “movement left,” the pack can understand what moved, where it went and what to do next.

WarpStream: Kafka-compatible streaming in the pack’s cloud

WarpStream keeps the Kafka-compatible Bark Line inside the pack’s own cloud while the story’s secret key protects stored messages. It introduces a modern approach to private, cloud-native event streaming without turning the adventure into a textbook.

Read the illustrated story to learn how events become records, streams gain context, and a team can act on continuously arriving information in real time.
