# Introduction
Followup of

close https://github.com/twentyhq/core-team-issues/issues/1910
We've completely decom the `sync-metadata` in production. We're now then
removing its implementation in favor of the v2.
## TODO:
- [x] Remove sync-metadata implem and commands
- [x] Remove workspace decorators
- [x] Type each deprecated field to deprecated on their workspaceEntity
- [x] Remove the `workspace-sync-metadata` folder entirely
- [x] remove workspace migration
- [x] workspace migration removal migration
- [x] remove the `v2` references from workspace manager file names
- [x] remove the `v2` references from workspace manager modules
- [ ] Double check impact on translation file path updates
## Note
- Removed the gate logic
- Remains some service v2 naming, serverless needs to be migrated on v2
fully
- Removed workspaceMigration service app health consumption, making it
always returning up ( no more down ) cc @FelixMalfait ( quite obsolete
health check now, will require complete refactor once we introduce inter
app dependency etc )
# Introduction
Added a `WorkspaceRelated` and `AllNonWorkspaceRelatedEntity` to
simplify the `FlatEntityFrom` that now do not expect a string literal to
omit and itself builds the related many to one entities foreign key
aggregators
We now have the type grain over relation to syncable or just workspace
related entities
Added a migrations that sets the fk on missing entities
## Next
In upcoming PR we will be able to introduce such below type
```ts
import { type CastRecordTypeOrmDatePropertiesToString } from 'src/engine/metadata-modules/flat-entity/types/cast-record-typeorm-date-properties-to-string.type';
import { type ExtractEntityManyToOneEntityRelationProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-many-to-one-entity-relation-properties.type';
import { type ExtractEntityOneToManyEntityRelationProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-one-to-many-entity-relation-properties.type';
import { type ExtractEntityRelatedEntityProperties } from 'src/engine/metadata-modules/flat-entity/types/extract-entity-related-entity-properties.type';
import { type RemoveSuffix } from 'src/engine/workspace-manager/workspace-migration-v2/workspace-migration-builder-v2/types/remove-suffix.type';
import { type SyncableEntity } from 'src/engine/workspace-manager/workspace-sync/types/syncable-entity.interface';
export type UniversalFlatEntityFrom<TEntity extends SyncableEntity> = Omit<
TEntity,
| `${ExtractEntityManyToOneEntityRelationProperties<TEntity> & string}Id`
| ExtractEntityRelatedEntityProperties<TEntity>
| 'application'
| 'workspaceId'

string as `${RemoveSuffix<P, 's'>}UniversalIdentifier`]: string;
} & {
[P in ExtractEntityOneToManyEntityRelationProperties<
TEntity,

string as `${RemoveSuffix<P, 's'>}UniversalIdentifiers`]: string[];
};
```
In this PR:
## Improve recompute metadata cache performance. We are aiming for
~100ms
Deleting relationMetadata table and FKs pointing on it
Fetching indexMetadata and indexFieldMetadata in a separate query as
typeorm is suboptimizing
## Remove caching lock
As recomputing the metadata cache is lighter, we try to stop preventing
multiple concurrent computations. This also simplifies interfaces
## Introduce self recovery mecanisms to recompute cache automatically if
corrupted
Aka getFreshObjectMetadataMaps
## custom object resolver performance improvement: 1sec to 200ms
Double check queries and indexes used while creating a custom object
Remove the queries to db to use the cached objectMetadataMap
## reduce objectMetadataMaps to 500kb

We used to stored 3 fieldMetadataMaps (byId, byName, byJoinColumnName).
While this is great for devXP, this is not great for performances.
Using the same mecanisme as for objectMetadataMap: we only keep byIdMap
and introduce two otherMaps to idByName, idByJoinColumnName to make the
bridge
## Add dataloader on IndexMetadata (aka indexMetadataList in the API)
## Improve field resolver performances too
## Deprecate ClientConfig
