Summary
이 논문은 데이터 스트림 관리 시스템(DSMS)에서 세분화된 프로베넌스(provenance) 관리를 위해 연산자 계측(operator instrumentation) 기법을 제안합니다. 쿼리 네트워크 내 여러 연산자를 수정하여 프로베넌스를 생성하고 전파하며, 실행 중 즉시 계산하거나 처리와 분리하여 런타임 오버헤드를 줄이는 방법을 다룹니다.
Key Points
- 데이터 스트림 관리 시스템(DSMS)에서 진단 및 디버깅을 위한 세분화된 프로베넌스 관리의 중요성 강조
- 연산자 계측(operator instrumentation)을 통한 프로베넌스 생성 및 전파 기법 제안
- 쿼리 실행 중 즉시 계산(eager computation)과 처리 분리(decoupling)를 통한 런타임 오버헤드 감소 연구
