Conversation
Add @Index decorators and a migration for commonly queried columns on the ReviewItem entity to avoid sequential scans as the table grows. ## Indexes added 1. `IDX_review_items_status` on `status` — covers the `WHERE status = 'pending'` filter used by `ManualReviewService.getQueue()`. 2. `IDX_review_items_safetyScore_createdAt` composite on `(safetyScore, createdAt)` — covers the `ORDER BY safetyScore DESC, createdAt ASC` sort used by `getQueue()` to prioritise high-risk items, then oldest-first. 3. `IDX_review_items_sourceType` on `sourceType` — supports lookups by source type for content-report linkage. 4. `IDX_review_items_sourceId` on `sourceId` — supports joins / filters by source identifier. 5. `IDX_review_items_reportId` on `reportId` — supports joins / filters by report identifier. ## Migration New migration `1807000000000-add-review-item-indexes.ts` creates the indexes with `CREATE INDEX IF NOT EXISTS` and drops them in reverse order in `down()`. The migration uses only the passed QueryRunner (no separate connections) and passes the `validate-migrations.js` CI check.

Well done on the job done so far! |
The added Index import pushed the single-line import past the 100-char print width, failing the prettier lint check in CI. Expand it to one specifier per line. 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>
