Summary

  • Add messaging.kafka.cluster.id tag to both producer and consumer Kafka spans, always (not gated on Data Streams)
  • Add broker-assigned partition and offset tags to producer spans via the async callback (using RecordMetadata)
  • Consumer spans already had partition and offset; no change there
  • Remove isDataStreamsEnabled() guard from extractClusterId() in KafkaConsumerInstrumentationHelper (both 0.11 and 3.8 modules)
  • Always initialize MetadataState in ProducerConstructorAdvice so cluster ID is available at produce time regardless of DSM config

These tags enable linking a trace span directly to a specific Kafka message (cluster + topic + partition + offset).

Notes

  • Producer offset is only set when a callback is used (it's a broker-assigned value returned asynchronously); fire-and-forget usage via Future will not have the offset tag
  • Both kafka-clients-0.11 and kafka-clients-3.8 modules updated in parallel

Test plan

  • Run ./gradlew :dd-java-agent:instrumentation:kafka:kafka-clients-0.11:test
  • Run ./gradlew :dd-java-agent:instrumentation:kafka:kafka-clients-3.8:test
  • Verify consumer span has messaging.kafka.cluster.id, partition, offset, kafka.group, and messaging.destination.name tags
  • Verify producer span has messaging.kafka.cluster.id, partition, offset, and messaging.destination.name tags

Add Kafka cluster ID, topic, consumer group, and offset tags to spans
f2a32a7 
Tag producer spans with messaging.kafka.cluster.id, topic, and
broker-assigned partition/offset (via callback). Tag consumer spans with
messaging.kafka.cluster.id, topic, consumer group, and offset. These tags
enable linking from a span directly to a specific Kafka message.

Previously the cluster ID was only extracted when Data Streams was enabled;
MetadataState is now always initialized on the producer so cluster ID flows
through regardless of DSM configuration.
