Next review available in: 31 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.

Inline comments:
In `@frontend/src/erd/prisma.ts`:
- Around line 62-63: Update the Prisma exporter around edgesProcessedByField in
frontend/src/erd/prisma.ts: pre-index each node’s columns so the Edge-level
columns.find lookup is removed and the implementation achieves O(N*C + E);
alternatively, document the actual O(N*C + E*C) complexity instead. Update
.jules/bolt.md lines 80-82 to claim O(N*C + E) only if the exporter is changed
to provide that guarantee; otherwise revise the documented complexity to match
the implementation.
- Around line 97-100: Update the relationship processing around
edgesProcessedByField so multiple edges sharing a source model and field are not
silently overwritten; either deduplicate them at field level or retain a per-key
collection and generate every relation consistently with
incomingRelationsByNode. Align the Prisma relation field normalization with FK
handling by applying the same src-/tgt- prefix removal used by sanitizeHandleId
before sanitizing edge.sourceHandle, ensuring identical columns resolve to the
same model and field.

💡 무엇을 (What):
exportPrisma함수 내부에서 각 컬럼을 순회할 때마다 생성된 Edge를 찾는 중첩 루프(배열 순회) 로직을 제거하고, 대신 O(1) 해시 맵(edgesProcessedByField) 조회를 사용하도록 리팩터링했습니다.🎯 왜 (Why):$O(N \cdot C \cdot E)$ 의 시간 복잡도를 가졌습니다. 이로 인해 다이어그램 크기가 커질수록 Prisma 스키마 내보내기 성능이 심각하게 저하되는 병목 현상이 발생했습니다.
이전 방식은 노드(N), 컬럼(C), 그리고 엣지(E)의 갯수에 비례하여
📊 예상 영향 (Impact):$O(N \cdot C + E)$ 로 낮춰 대규모 데이터베이스 구조에서도 빠른 추출 성능을 기대할 수 있습니다.
Prisma 내보내기의 시간 복잡도를
🔬 검증 방법 (Measurement):
pnpm run test를 통해 리팩터링 후에도 기존 로직과 동일하게 작동하며 어떠한 부작용도 발생하지 않음을 검증했습니다.PR created automatically by Jules for task 372933566554818287 started by @seonghobae

2f95b8ec68c672473b978fe559bdee4ae01f85e2closes both current review findings. Node columns are pre-indexed by canonical handle/name, outgoing relations are stored per source field without overwrite, and output lookup is O(N*C + E). Test-first evidence: canonical handles and two relations sharing one source field produced no relation objects before the fix; focused Prisma tests now pass 9/9. Full frontend rerun: 27 files / 198 tests passed; typecheck and production build passed.
