https://sonarly.com/issue/3775?type=bug The `FindAllCoreViews` query generates a single SQL statement with 6 LEFT JOINs across 5 independent one-to-many relationships, creating a cartesian product explosion that takes 1618ms. Caching masks the issue for most requests, but cache misses cause ~2s page loads. Fix: The `findByWorkspaceId` method in `view.service.ts` loaded 6 relations via TypeORM's default `join` strategy, which generates a **single SQL statement with 6 LEFT JOINs**. When 5 of those are independent one-to-many relationships (viewFields, viewFilters, viewSorts, viewGroups, viewFilterGroups), the result set explodes combinatorially — a view with 20 fields × 5 filters × 3 sorts × 5 groups × 2 filter groups yields 3,000 rows for a single view. Two changes were made: **1. Add `relationLoadStrategy: 'query'`** — instructs TypeORM to issue one `SELECT … WHERE viewId IN (…)` per relation instead of a single monolithic JOIN query. This avoids the cartesian product entirely. Available since TypeORM 0.3.12; the project uses 0.3.20. **2. Remove the `'workspace'` relation** — the `workspace` ManyToOne (inherited from `WorkspaceRelatedEntity`) adds 30+ workspace columns to every row of the result set. It is not needed: `ViewDTO` only exposes `workspaceId` (a scalar column already on the view row), and no call site downstream uses `view.workspace`. ```typescript file=packages/twenty-server/src/engine/metadata-modules/view/services/view.service.ts lines=380-395 const views = await this.viewRepository.find({ where: { workspaceId, deletedAt: IsNull(), ...(viewTypes && viewTypes.length > 0 && { type: In(viewTypes) }), }, order: { position: 'ASC' }, relations: [ 'viewFields', 'viewFilters', 'viewSorts', 'viewGroups', 'viewFilterGroups', ], relationLoadStrategy: 'query', }); ``` After the fix TypeORM will issue 6 lean, targeted queries (one per relation) rather than one 120-column cartesian-product query, reducing the expected cache-miss latency from ~1600ms to well under 100ms.

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
