v12.127.0

Warning

⚠️ This release contains some breaking changes ⚠️

🛠️ Fixes and enhancements

• @zarirhamza AWS Service Naming Overhaul (#655, #666)
  • ⚠️ Service names are now reflect the actual AWS resource name instead of being vague. The old to new mappings are:
    • aws.lambda → [function_name]
    • aws.dynamodb → [table_name]
    • aws.sns → [topic_name]
    • aws.sqs → [queue_name]
    • aws.kinesis → [stream_name]
    • aws.s3 → [bucket_name]
    • aws.eventbridge → [event_name]
  • To opt out and restore old behavior, use the env var:

    DD_TRACE_AWS_SERVICE_REPRESENTATION_ENABLED=false

  • Dashboards, monitors, or alerts using service as a filter may break.
    • Recommended fix: Switch to using operation_name with same value to achieve old behavior.
  • Sampling rules may need to be updated to reflect the new service names

Other Changes

• DD_SERVICE now takes precedence when setting the service name on Lambda spans.
• AWS spans are now correctly marked with span.kind: server.
• Removed outdated service override logic
• Cold start tracing config now uses a boolean (true / false) instead of numeric (1 / 0).
