Description

• SpaceConnector.dispatch: CLIENT span 으로 래핑 (외부 요청 표현)
• transaction 데코레이터: SERVER span 설정 (내부 요청 표현)

해당 변경으로 트레이스의 정확성과 관찰성을 개선합니다.

---

Known issue

• 현재 span kind 는 SpaceConnector(client)와 transaction(server) 데코레이터에만 적용되었기 때문에, 이 구조를 따르지 않는 트레이스의 경우 추적이 어려울 수 있습니다.
• console-api-v2 등을 통해서 호출되지 않고 내부적으로 호출되는 호출 사항에 대한 trace 는 명확히 trace 하기 어려울 수 있습니다.
