## Context
`isCustom` was a legacy denormalized boolean on `ObjectMetadataEntity`
and `FieldMetadataEntity`.
Now that every metadata row carries `applicationId` (via
`SyncableEntity`), "is this custom" is fully derivable, and the stored
boolean was a redundant second source of truth that could drift.
The real meaning of `isCustom` is **"the owning application is not the
twenty-standard application"** — i.e. `!belongsToTwentyStandardApp`.
Note this is *not* "belongs to the workspace custom app" as I initially
thought: third-party-application
objects/fields are custom too.
The standard application has a globally stable `universalIdentifier`, so
the value derives with no per-workspace lookup.
## Changed
## `isCustom` checks — before → after
`isCustom` is no longer a stored column. The table below lists every
site that branched on it and how it resolves now. The unifying rule:
`isCustom ≡
!isTwentyStandardApplicationUniversalIdentifier(applicationUniversalIdentifier)`.

is never used in the FE and unlikely used by external consumers
## What
Many `oxlint-disable` / `eslint-disable` directives across the repo
carry a corrupted rule id — `@typescripttypescript/<rule>` — most likely
a find-and-replace accident that mangled the eslint-era
`@typescript-eslint/` prefix.
oxlint matches disable directives **loosely by rule name**, so these
still suppress in practice (not a silent no-op), but the id is malformed
and misleading.
## Change
Replace them with the **canonical oxlint id** `typescript/<rule>` —
matching the plugin name and rule keys declared in `.oxlintrc.json` —
**127 files, 262 directives**:
| rule | count |
| --- | ----- |
| `typescript/no-explicit-any` | 250 |
| `typescript/ban-ts-comment` | 6 |
| `typescript/no-misused-promises` | 4 |
| `typescript/no-empty-object-type` | 2 |
- `twenty-server`: 122 files
- `twenty-front`: 5 files
Comment-only — no code or runtime changes.
## Verification
`oxlint --type-aware -c .oxlintrc.json` reports **0 warnings / 0
errors** for both `twenty-server` and `twenty-front`. Every changed line
is exactly the id correction inside a disable directive (262 insertions
/ 262 deletions, no collateral edits).
> Addresses the cubic review, which flagged that the canonical oxlint id
is `typescript/...` (no `@`). Worth noting the original
`@typescripttypescript/` was not actually a silent no-op — oxlint
matches these directives loosely by rule name — but `typescript/` is the
correct, config-aligned id.
## Summary
Closes#20195
Fix phone field unique constraints so phone numbers are considered
unique by both `primaryPhoneNumber` and `primaryPhoneCallingCode`.
- Include `primaryPhoneCallingCode` in the shared phone composite unique
constraint metadata
- Align the frontend settings composite field config with the backend
metadata
- Return all included unique composite subfields when building
create-many conflict fields
- Match composite unique conflict fields as a group during create-many
upserts
## Root Cause
Phone composite metadata only marked `primaryPhoneNumber` as part of the
unique constraint. That made different international phone numbers with
the same national number conflict, for example `+1 123456789` and `+32
123456789`.
## Test Plan
- `yarn workspace twenty-shared build`
- `jest --runTestsByPath <index action handler and create-many utility
specs>`
- `prettier --check <touched files>`
- `oxlint --type-aware <touched files>`
- `nx run twenty-shared:typecheck`
- `nx run twenty-server:typecheck`
- `nx run twenty-front:typecheck`

## Summary
- **Drop the `objectMetadata.dataSourceId` foreign key and index** via a
1-22 fast instance command — column kept nullable for data preservation
- **Delete `DataSourceService`, `DataSourceModule`, and
`DataSourceException`** — all code now uses `workspace.databaseSchema`
directly
- **Remove `IS_DATASOURCE_MIGRATED` feature flag** from default flags
and all branching logic
- **Simplify workspace/object creation pipelines** —
`WorkspaceManagerService`, `DevSeederService`, and the object creation
action handler no longer route through `DataSourceService`
- **Keep `DataSourceEntity` and the `dataSource` table** for historical
data — entity stripped of all ORM relations
## Summary
- Consolidates duplicated auth-context-to-role-ID resolution logic
(previously in
`PermissionsService.resolveRolePermissionConfigFromAuthContext` and
`CommonBaseQueryRunnerService.getRoleIdOrThrow`) into a single pure
utility function `resolveRolePermissionConfig` in the ORM layer
- The utility is synchronous and operates on cached data
(`userWorkspaceRoleMap`, `apiKeyRoleMap`) already loaded into the
workspace context — no async calls, no service dependencies
- Adds `apiKeyRoleMap` to `ORMWorkspaceContext` (it was already in the
workspace cache, just not loaded into the ORM context)
- Removes `PermissionsService` dependency from
`NavigationMenuItemRecordIdentifierService`
- Removes `UserRoleService` and `ApiKeyRoleService` injections from
`CommonBaseQueryRunnerService`
## Test plan
- [ ] Existing typecheck passes (`npx nx typecheck twenty-server`)
- [ ] Verify record identifier resolution still works for navigation
menu items (user, system, API key, and application auth contexts)
- [ ] Verify GraphQL CRUD queries still enforce correct role-based
permissions
- [ ] Verify API key authenticated requests resolve permissions
correctly
Made with [Cursor](https://cursor.com)
Workflow crons take a few minutes to run. Loading each repo takes ~200
to 300ms locally. Adding a lite mode so it takes less than 100ms.
Also doing batch promises.
Finally, cleaning runs timeout when there are too many. Doing batches as
well.
## Context
The previous WorkspaceAuthContext was a single interface with many
optional fields, making it unclear which fields are available in
different authentication scenarios. This made the code harder to reason
about and required runtime checks scattered throughout the codebase.
## Changes
- Introduced a discriminated union type for WorkspaceAuthContext with
four specific variants:
-> UserWorkspaceAuthContext - for authenticated users
-> ApiKeyWorkspaceAuthContext - for API key authentication
-> ApplicationWorkspaceAuthContext - for application-based auth
-> SystemWorkspaceAuthContext - for system/internal operations
- Added type guard functions (isUserAuthContext, isApiKeyAuthContext,
etc.) for safe type narrowing
- Added builder utilities (buildUserAuthContext, buildApiKeyAuthContext,
etc.) to construct each context variant with proper type safety
- Refactored WorkspaceAuthContextMiddleware to use the new builders
instead of constructing a loosely-typed object
- Moved the type definition from twenty-orm/interfaces/ to
core-modules/auth/types/ for better organization
- Updated all consumers across query runners, tool providers, and
modules to use the new type location
## Notes
- I had to query User and WorkspaceMember in some parts of tool module
that were expecting userWorkspaceId but not the rest of
UserWorkspaceAuthContext (that should be required with the new proper
type otherwise it would break a lot of logic and mostly permissions with
the newly added RLS -> This is what we expect from
UserWorkspaceAuthContext and how it's done in the "normal" path in HTTP
middleware)
- WorkspaceMember is in the cache already but ideally we should move
User (And Workspace?) in the cache as well to avoid querying the DB
after each request (this is also valid for HTTP middleware when we
hydrate the Request object btw)
## Context
Introduces a middleware that automatically sets the workspace auth
context in AsyncLocalStorage for HTTP requests, making it available
throughout the request lifecycle without explicit parameter passing.
The motivation behind this change is to reduce boilerplate and simplify
the developer experience when working with workspace data in HTTP
request handlers.
The Problem (Before)
Every HTTP request handler that needed to access workspace data had to:
- Extract auth-related info from decorators (@AuthWorkspace(),
@AuthUserWorkspaceId(), etc.) in controller/resolver and pass down to
services
- Build or pass the authContext explicitly (sometimes with type
assertion which was flaky)
Then call executeInWorkspaceContext(authContext, async () => { ... })
## Changes
- Add WorkspaceAuthContextMiddleware that extracts auth context from the
request and stores it in AsyncLocalStorage
- Register middleware for GraphQL, metadata, and REST routes (runs after
hydration middlewares)
- Simplify executeInWorkspaceContext signature: fn is now the first
parameter, authContext is optional second
- If authContext is not provided, it's automatically retrieved from the
storage (set by middleware)
- Update all callers (~120 files) to use the new parameter order
- Fixes a bug in search where system auth context was used, bypassing
RLS feature.

Removing the feature flag to enable read on replica for all workspaces.
It will still be possible to toggle off the feature by removing the env
variable `PG_DATABASE_REPLICA_URL`.
## Context
Following https://github.com/twentyhq/twenty/pull/16399
Now using the new global orm manager everywhere and returning a
GlobalDatasource/WorkspaceDatasource based on a feature flag.
This means we now need to wrap all our ORM calls within
executeInWorkspaceContext callback (at least for now) so the global
datasource can dynamically hydrate its context via the new store (the
global datasource does not store anything related to workspaces as it is
now a unique singleton). If feature flag is off it still uses local data
stored in the workspace datasource.
## Problem
buildEntityMetadatas in GlobalWorkspaceOrmManager is computationally
expensive and was running on every executeInWorkspaceContext call. This
method uses
TypeORM's EntitySchemaTransformer and EntityMetadataBuilder to build
metadata for all workspace entities (30-50+ objects with many fields
each).
The resulting EntityMetadata[] is not serialisable which means it cannot
be cached in Redis because they contain:
- Circular references
- Functions/methods
- References to the DataSource instance
## Solution
Extended the workspace cache system to support local-only caching, then
created a cache provider for entityMetadatas.
## Implementation details
Updated @WorkspaceCache decorator (workspace-cache.decorator.ts)
- Added localOnly?: boolean option to skip Redis storage for
non-serializable data
Created WorkspaceEntityMetadatasCacheService
- Computes entity metadatas from DB to avoid race condition, this is
acceptable
Simplified GlobalWorkspaceOrmManager
- Now fetches entityMetadatas from cache instead of rebuilding on every
call
Updated Workspace migration runner - the only entry point where metadata
can change
- Now invalidate the new 'entityMetadata' local cache when
shouldIncrementMetadataGraphqlSchemaVersion is true (== field/object
mutations)
## Context
We've recently introduced a new workspace cache service which now acts
as a cache access and local storage for all workspace related data,
deprecating the individual specific services.
- Better performance through multiple caching/fetching strategies
- Consistent data access patterns across the codebase
- Reduced redis queries through MGET/MSET/PIPELINE with multiple cache
keys
## Context
EntityMetadata was being rebuilt from scratch on every
findMetadata()/getMetadata() call (~20 times per request). This involved
running EntitySchemaTransformer.transform() and
EntityMetadataBuilder.build() repeatedly, causing unnecessary CPU
overhead.
## Implementation
Cache entityMetadatas in ORMWorkspaceContext: Build EntityMetadata once
during workspace context initialization instead of on every metadata
lookup
Remove redundant entitySchemas caching: Since flatMetadata is already
cached, the additional Redis cache for entitySchemaOptions was
unnecessary overhead
Remove WorkspaceEntitiesStorage: Replaced with direct lookup from
FlatObjectMetadataMap
Simplify getObjectMetadataFromEntityTarget: Now only accepts string
targets, using flat metadata maps directly
Also:
Removed unused injections in some services
## Context
Deprecating the old objectMetadataMap type in favour of split flat
entities to match with our new caching.
In the long run, trying to achieve:
- Better performance through caching
- Consistent data access patterns across the codebase
- Reduced database queries
Now that everything is based on flat entities, which are cached, we can
finish the refactoring of workspace context cache which should already
improve performances.
Then the last step will be to consume that new cache in the new global
datasource to get rid of the many workspace datasources stored in the
server
## Context
Deprecating legacy ObjectMetadata from cache in favor of flat entities.
Introducing utils to build byName/byNameSingular/byNamePlural in
isolated cases
## Next
- I had to introduce a util to build from flat to legacy
objectMetadataMaps, we should instead use flat maps directly when needed
(datasource, schema generation, etc)
- Deprecate metadata version in the cache
- Use the new cache strategy for flat entities with permissions and
feature flags and inject in the global datasource context
## Context
Implementing a single service managing all the cache scoped to a
workspace, this will be dynamically injected as a WorkspaceContext in
the app during a request lifetime (ingested by the future global
datasource for example).
Usage:
```typescript
this.globalWorkspaceOrmManager.executeInWorkspaceContext(
authContext,
async () => {
// Everything here will have access to a workspaceContext, containing all the cache data + a ready to use datasource with workspace scoped metadata, permissions, feature flags, etc...
// Internally will call loadWorkspaceContext
}
```
Note: executeInWorkspaceContext will probably be owned by a higher level
service later and not only the ORM.
```typescript
private async loadWorkspaceContext(
authContext: WorkspaceAuthContext,
): Promise<WorkspaceContext> {
const workspaceId = authContext.workspace.id;
const cache =
await this.workspaceContextCacheService.get<WorkspaceContextData>(
workspaceId,
[
'objectMetadataMaps',
'metadataVersion',
'featureFlagsMap',
'permissionsPerRoleId',
],
);
return {
authContext,
objectMetadataMaps: cache.objectMetadataMaps,
metadataVersion: cache.metadataVersion,
featureFlagsMap: cache.featureFlagsMap,
permissionsPerRoleId: cache.permissionsPerRoleId,
};
}
```
The cache retrieval strategy is as followed:
```
- Check if there is an ongoing promise fetching data from the cache =>
return the promise.
- Check in the local cache entry if lastCheckedAt has expired. If not,
return as it is without querying redis.
- Check in redis the cache entry hash and compare with local cache entry
hash, if they are the same return the local cache entry data
- Check in redis the cache entry data, if it's there return it and store
it into the local cache entry data and update local cache entry hash. If
it's not there recompute the data by querying the DB and update both
redis and local cache
```
Fixes https://github.com/twentyhq/twenty/issues/15809
## Context
We recently introduced a global datasource now consuming workspace
context from ALS store however the authContext was missing (only the
workspaceId was there) which "broke" event emission, now missing the
workspaceMemberId
This PR adds the missing authContext so we can access from anywhere in
the datasource. We are still passing it as a parameters on repository
level for legacy but in theory we should be able to remove it from
everywhere and consume the context

## Context
inferDeletionFromEntities only accepts a set of keys for each entities
that needs deletion. This could be error-prone if tmr we want to add a
new side effect and forget to add the entity when in practice you want
to delete all entities that are in the fromToAllFlatEntityMaps (this is
the case for applications for example)
## Context
This PR introduces a Global Workspace DataSource that consolidates
workspace-specific database access through a single TypeORM DataSource
instance with AsyncLocalStorage-based context management instead of N
workspace datasources.
- Created GlobalWorkspaceDataSource extending TypeORM's DataSource to
manage multiple workspaces with entity metadata caching (1-hour TTL)
- Implemented AsyncLocalStorage for workspace context propagation
(WorkspaceContextForStorage) containing workspace ID, metadata,
permissions, and feature flags
- Modified query execution flow to wrap operations in workspace context
via GlobalWorkspaceOrmManager.executeInWorkspaceContext()
- Added schema name to entity schemas for proper multi-tenant database
separation
Next:
- use the new global workspace datasource everywhere and deprecate
workspace datasource factory
- improve metadata caching using a short TTL to avoid multiple calls to
redis
- Leverage the new WorkspaceContextALS and put it higher in the request
hierarchy to have access to permission, metadata and featureflag
everywhere --- build it manually for commands --- find a way to
propagate it in jobs?
- Remove PG_POOL patch once we have a unique datasource and increase
global datasource pool size
## Implementation
Why ALS:
1. Automatic Per-Request Isolation
With schema-based multi-tenancy, each workspace has its own PostgreSQL
schema
(e.g. workspace_20202020-1c25-4d02-bf25-6aeccf7ea419).
The critical challenge is ensuring that concurrent requests from
different tenants don't interfere with each other.
```typescript
// Request A (Workspace 1) and Request B (Workspace 2) executing concurrently
// Without ALS: Race condition — they'd share the same global state!
// With ALS: Each request has isolated context ✓
```
ALS automatically isolates context per async execution chain, so:
- Request from Tenant A → ALS stores workspaceId: "tenant-a" → Queries
hit workspace_tenant_a schema
- Request from Tenant B → ALS stores workspaceId: "tenant-b" → Queries
hit workspace_tenant_b schema
✅ No interference, even when executing simultaneously on the same
Node.js event loop.
2. No Manual Context Passing
Before ALS, you'd need to pass workspaceId through every function call:
```typescript
// ❌ Without ALS - Context threading nightmare
getRepository(workspaceId, entity)
→ createEntityManager(workspaceId)
→ getMetadata(workspaceId, target)
→ findInCache(workspaceId, cacheKey)
```
With ALS:
```typescript
// ✅ With ALS - Clean, implicit context
getRepository(entity) // Reads workspaceId from ALS
→ createEntityManager() // Reads workspaceId from ALS
→ getMetadata(target) // Reads workspaceId from ALS
→ findInCache(cacheKey) // Reads workspaceId from ALS
```
example
```typescript
override findMetadata(target: EntityTarget<ObjectLiteral>): EntityMetadata | undefined {
const context = getWorkspaceContext(); // 👈 Automatically gets the right workspace!
const { workspaceId, metadataVersion } = context;
const cacheKey = `${workspaceId}-${metadataVersion}`;
// ... returns metadata for THIS workspace's schema
}
```
3. Async Chain Propagation
Node.js operations are heavily async. ALS automatically propagates
context through:
- async/await chains
- Promise chains
- Callbacks
```typescript
executeInWorkspaceContext(workspaceId, async () => {
await prepareContext(); // Has context ✓
const results = await run(); // Has context ✓
await enrichResults(); // Has context ✓
// Even nested async operations maintain context!
await Promise.all([
saveToCache(), // Has context ✓
emitEvent(), // Has context ✓
logMetrics(), // Has context ✓
]);
});
```
5. Schema-Specific Metadata Caching
The implementation caches entity metadata per workspace + version:
```typescript
// Cache key format: "workspaceId-metadataVersion"
const cacheKey = `${workspaceId}-${metadataVersion}`;
```
Why this matters with schemas:
- Each workspace has different table structures (custom fields, objects)
- EntitySchema includes schema: "workspace_xxx" property
- Each cached metadata points to the correct schema
ALS ensures getWorkspaceContext() returns the right workspaceId,
so you always get the correct schema's metadata from cache.
6. Single DataSource for All Tenants
The key change here:
```typescript
// ❌ Old approach: One DataSource per tenant
const dataSourceTenantA = new DataSource({ schema: 'workspace_a' });
const dataSourceTenantB = new DataSource({ schema: 'workspace_b' });
// Problem: Hundreds of DB connection pools!
```
```typescript
// ✅ New approach: One shared DataSource + ALS context
const globalDataSource = new GlobalWorkspaceDataSource();
// ALS determines which schema to use at runtime
```
When you call:
```typescript
globalDataSource.getRepository('person');
```
It internally does:
```typescript
const context = getWorkspaceContext(); // Gets current tenant from ALS
const metadata = this.findMetadata('person'); // Finds metadata for THIS tenant's schema
// EntityMetadata includes: schema: "workspace_20202020-1c25..."
// TypeORM automatically queries: SELECT * FROM "workspace_20202020-1c25...".person
```
7. Request Lifecycle Example
```typescript
// 1. GraphQL request arrives: "query people { ... }"
// 2. Middleware extracts authContext.workspace.id = "tenant-a"
// 3. Query runner wraps execution in ALS:
executeInWorkspaceContext("tenant-a", async () => {
// 4. Everything inside has access to workspace context:
const repo = getRepository('person'); // ALS → tenant-a
const metadata = getMetadata('person'); // ALS → tenant-a → cache["tenant-a-v5"]
// 5. TypeORM builds query with correct schema:
// SELECT * FROM "workspace_tenant_a"."person" WHERE ...
// 6. Even nested calls work:
await saveAuditLog(); // ALS → tenant-a → correct audit schema
await emitWebhook(); // ALS → tenant-a → correct tenant webhook
});
// 7. Request completes, ALS context automatically cleaned up
```
8. Safety & Error Prevention
```typescript
// If you forget to set context:
const context = getWorkspaceContext();
// ❌ Throws: "Workspace context not set..."
// Fails fast rather than querying wrong schema!
// Can't accidentally query wrong tenant:
// Context is immutable within execution scope
```
