Kafka functions

A function can consume messages from an Apache Kafka topic. When a function declares a run.kafka configuration, func deploys a language-agnostic runtime sidecar alongside it. The sidecar consumes the topic and delivers each record to the function as a CloudEvent over HTTP, so the function stays a plain CloudEvents handler in any language, with no Kafka client code of its own.

The full guide lives in the func repository, covering concepts, a getting-started walkthrough, delivery and retries, deployment and scaling, idempotency, local development, and troubleshooting:
