## Summary Introduces multi-layer caching for the 5 most frequent database queries identified in production (Sentry data), targeting the JWT authentication hot path and cron job logic. ### Problem Our database is under heavy load from uncached queries on the auth hot path: - `WorkspaceEntity` lookups: **638 queries/min** - `ApiKeyEntity` lookups: **491 queries/min** - `UserEntity` lookups: **147 queries/min** - `UserWorkspaceEntity` lookups: **143 queries/min** - `LogicFunctionEntity` lookups: **1800 queries/min** (cron job) ### Solution **1. New `CoreEntityCacheService`** for non-workspace-scoped entities (Workspace, User, UserWorkspace): - Mirrors `WorkspaceCacheService` architecture (in-process Map + Redis with hash validation) - Provider pattern with `@CoreEntityCache` decorator - Keyed by entity primary key (not workspaceId) - 100ms local TTL, Redis-backed hash validation for cross-instance consistency - Three providers: `WorkspaceEntityCacheProviderService`, `UserEntityCacheProviderService`, `UserWorkspaceEntityCacheProviderService` **2. New `apiKeyMap` WorkspaceCache** for workspace-scoped API key lookups: - `WorkspaceApiKeyMapCacheService` loads all API keys for a workspace into a map by ID - Leverages existing `WorkspaceCacheService` infrastructure - Cache invalidation on API key create/update/revoke **3. `CronTriggerCronJob` refactored** to use existing `flatLogicFunctionMaps` workspace cache: - Eliminates per-workspace `LogicFunctionEntity` repository queries (~1800/min) - Filters cached data in-memory instead **4. `JwtAuthStrategy` refactored** to use caches for all entity lookups: - Workspace, User, UserWorkspace → `CoreEntityCacheService` - ApiKey → `WorkspaceCacheService` (`apiKeyMap`) - Impersonation queries kept as direct DB queries (rare path, requires relations) **5. Cache invalidation** wired into mutation paths: - `WorkspaceService` → invalidates `workspaceEntity` on save/update/delete - `ApiKeyService` → invalidates `apiKeyMap` on create/update/revoke ### Architecture ``` Request → JwtAuthStrategy ├── Workspace lookup → CoreEntityCacheService (in-process → Redis → DB) ├── User lookup → CoreEntityCacheService (in-process → Redis → DB) ├── UserWorkspace lookup → CoreEntityCacheService (in-process → Redis → DB) └── ApiKey lookup → WorkspaceCacheService (in-process → Redis → DB) CronTriggerCronJob └── LogicFunction lookup → WorkspaceCacheService (flatLogicFunctionMaps) ``` ### Expected Impact | Query | Before | After | |-------|--------|-------| | WorkspaceEntity | 638/min | ~0 (cached) | | ApiKeyEntity | 491/min | ~0 (cached) | | UserEntity | 147/min | ~0 (cached) | | UserWorkspaceEntity | 143/min | ~0 (cached) | | LogicFunctionEntity | 1800/min | ~0 (cached) | ### Not included (ongoing separately) - DataSourceEntity query optimization (IS_DATASOURCE_MIGRATED migration) - ObjectMetadataEntity query optimization (already partially cached)

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.
