Next review available in: 23 minutes You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window. Please refer docs for additional details. Review details⚙️ Run configurationConfiguration used: Organization UI Review profile: CHILL Plan: Pro Plus Run ID: 📒 Files selected for processing (4)

💡 What:
데이터베이스 풀러 탐지 로직이 기존 순차적 방식에서
asyncio.wait의FIRST_COMPLETED옵션을 활용한 동시성 처리 방식으로 최적화되었습니다. 가장 빠른 응답을 즉시 반환하고 백그라운드의 불필요한 Task는finally블록에서 안전하게 취소(cancel)하도록 개선되었습니다.🎯 Why:
이전의 순차적 탐지 로직은 첫 번째 프로브 대상(예: PgBouncer)이 접근 불가능하거나 연결이 타임아웃 될 때까지 기다려야 했기 때문에, 두 번째 대상(예: PgCat)이 존재함에도 불구하고 최악의 경우 연결 지연이 발생했습니다.
📊 Measured Improvement:
로컬 테스트에서 순차 탐지 시 2초(PgBouncer 2초 대기 + PgCat 0.1초 소요) 이상 걸리던 작업이, 동시 탐지 구현 후 0.10s (PgCat의 실 소요 시간)로 단축되어 불필요한 레이턴시 병목이 해소되었습니다.
