| description | Use when you need Kafka messaging in Quarkus with SmallRye Reactive Messaging — including channel/topic design, build-time Jackson serialization, typed @Channel/@Incoming, ack/failure strategies, retries/DLQ, idempotency, Dev Services, and Testcontainers integration tests. This should trigger for requests such as Add Kafka in Quarkus; Review Reactive Messaging consumers; Improve failure handling for Quarkus Kafka. Part of cursor-rules-java project |

Quarkus — Kafka messaging
Apply Quarkus Kafka guidance with concrete examples for design, implementation, and error handling.
Constraints
Compile before messaging refactors; verify after changes.
- MANDATORY: Run
./mvnw compile or mvn compile before applying any change
- SAFETY: If compilation fails, stop immediately
- VERIFY: Run
./mvnw clean verify or mvn clean verify after applying improvements
- BEFORE APPLYING: Read the reference for detailed rules and examples
When to use this skill
- Add Kafka in Quarkus
- Review Quarkus Reactive Messaging consumers/producers
- Improve retries, dead-letter handling, or idempotency in Quarkus Kafka
Workflow
- Read reference and assess project context
Read references/414-frameworks-quarkus-kafka.md and inspect current messaging setup before proposing changes.
- Gather scope and decide target improvements
Identify delivery semantics and resilience goals to define safe improvements.
- Apply framework-aligned changes
Implement/refactor channels, serializers, and failure strategies in Reactive Messaging.
- Run verification and report results
Execute build/tests and summarize what changed, what was verified, and follow-up actions.
