[Slow db query] Resolve applicationId from cache in FileStorageService (#22870)
## Context Sentry flagged a recurring slow DB query (TWENTY-SERVER-HZJ): `SELECT ... FROM core.application WHERE workspaceId = $1 AND universalIdentifier = $2 AND deletedAt IS NULL LIMIT 1`, emitted on every file write under `POST /graphql` (record avatar/file fields) and `POST /metadata`. `FileStorageService` re-resolved the owning application row from `core.application` by `(workspaceId, universalIdentifier)` on every file write, uncached and synchronously in the request path. The row was only used to recover `application.id`. The workspace cache already exposes this mapping via `flatApplicationMaps.idByUniversalIdentifier`. Closes twentyhq/core-team-issues#2668. ## Changes - Injected `WorkspaceCacheService` into `FileStorageService` in place of the `ApplicationEntity` repository. - Added `resolveApplicationIdOrThrow`: resolves `applicationId` from `flatApplicationMaps.idByUniversalIdentifier` on the normal (already-committed) path, throwing `FileStorageException(FILE_NOT_FOUND)` on a cache miss. When a `queryRunner` is provided (application-creating transactions, where the freshly created row is not yet in cache), it keeps the DB read through `queryRunner.manager` so it can see uncommitted rows. - Added `resolveApplicationUniversalIdentifierOrThrow` for the by-id lookup in `deleteByFileId`, resolved from `flatApplicationMaps.byId`. - Applied the cache path to `writeFile`, `createPendingFile`, `deleteFile`, `deleteFolder`, and `deleteByFileId`. Only `writeFile` carries a `queryRunner`; the others never do. - Updated `FileStorageModule` to import `WorkspaceCacheModule` and drop the now-unused `ApplicationEntity` repository registration. No migration needed: a partial unique composite index on `(universalIdentifier, workspaceId) WHERE deletedAt IS NULL AND universalIdentifier IS NOT NULL` already exists on `ApplicationEntity` and covers the query. ## Tests Extended `file-storage.service.spec.ts`: - cache hit resolves `applicationId` without a DB call, - cache miss throws `FILE_NOT_FOUND`, - the `queryRunner` path still reads from the DB and skips the cache. All 95 file-storage unit tests pass; typecheck, oxlint, and oxfmt are clean on the touched files. --- _Generated by [Claude Code](https://claude.ai/code/session_018GUrJ26xvZpjtrGGev9jsk)_ <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22870?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
