# Introduction
Extracting the legacy fields build and dispatch out of the object one to
follow the generic flat entity build, also update caches entries for
object
## Main tasks
- flat field map cache
- flat field builder
- refactored the dispatch matrix to return flat entity maps instead of
flat entity arrays
- orchestrator aggregator
- removing legacy code
- making universal identifier aka standardId of standard field for
custom object deterministically dynamic
- perfs debug logs for v2
## TODO
- [x] Refactor the generic entity builder to be dependency flat maps in
order to main foreign keys list in flat parent
- [x] Refactor the flat object metadata to contain the array of related
fields and avoid costy find object fields
- [ ] Improve the create field handler to handle multiple field at once
- [ ] Refactor the dispatch to embbed the comparison
- [ ] Improve perf by extracting from elements out of existing
- [ ] Fix the labelIdentifierId validators on object before field
creation ( integ tests are in failing mode )

As you can see cache invalidation is way to long, we could replace the
cache by the optimistic in the end
# Introduction
Honestly this implem is a mess, discussing a potential side effect
handler with @weiko before the build and run that would handle each side
effect per entity and operation
Handling:
- [ ] unique index is generated when a field is updated with the
`isUnique`
- [x] an index is generated when a relation is created
- [x] search vector index creation on custom object creation
- [x] renaming a field metadata or an object should re-create all
related indexes which are composed by their namings
- [x] delete object should remove any related indexes
- [x] delete field should update related indexes ( if index ends up
empty it should be removed )
- [ ] on object renaming that contains morph fields -> triggers update
field -> trigger index recompute
- [x] on update name renaming should recompute all related indexes
## TODO
- [x] Integration testing
- [ ] Refactor the index maps cache to be storing a
`idsByObjectMetadataId`
- [x] Refactor deterministic name to use order sorting
- [x] Remove flat index from flat object
## What's next
Will handle morph indexes in a new dedicated PR for the moment will
stick to this
Same for the cache improvement and uniqueness
Done :
- add isUnique prop availability on gql update/create fieldMetadata
resolvers
- add unique index creation logic at update & creation
- add unique index deletion logic at update
- update unique index if field name updated
- edge cases : can't have default value and unique fields / standard
default value excluded from index (where clause) / can't have composite
unique fields / can't create unique fields on MORPH
closes https://github.com/twentyhq/core-team-issues/issues/1222
In this PR
- introduction of fieldPermission entity
- addition of upsertFieldPermission in role resolver
- computing of permissions taking fieldPermission into account. In order
to limit what is stored in Redis we only store fields restrictions. For
instance for objectMetadata with id XXX with a restriction on field with
id YYY we store:
`"XXX":{"canRead":true,"canUpdate":false,"canSoftDelete":false,"canDestroy":false,"restrictedFields":{"YYY":{"canRead":false,"canUpdate":null}}}`

## Context
Our Flexible Schema engine dynamically generates entities/tables/APIs
for us but was not flexible enough to build indexes in the DB. With more
and more features involving heavy queries such as Messaging, we are now
adding a new WorkspaceIndex() decorator for our standard objects (will
come later for custom objects). This decorator will give enough
information to the workspace sync metadata manager to generate the
proper migrations that will create or drop indexes on demand.
To be aligned with the rest of the engine, we are adding 2 new tables:
IndexMetadata and IndexFieldMetadata, that will store the info of our
indexes.
## Implementation
```typescript
@WorkspaceEntity({
standardId: STANDARD_OBJECT_IDS.person,
namePlural: 'people',
labelSingular: 'Person',
labelPlural: 'People',
description: 'A person',
icon: 'IconUser',
})
export class PersonWorkspaceEntity extends BaseWorkspaceEntity {
@WorkspaceField({
standardId: PERSON_STANDARD_FIELD_IDS.email,
type: FieldMetadataType.EMAIL,
label: 'Email',
description: 'Contact’s Email',
icon: 'IconMail',
})
@WorkspaceIndex()
email: string;
```
By simply adding the WorkspaceIndex decorator, sync-metadata command
will create a new index for that column.
We can also add composite indexes, note that the order is important for
PSQL.
```typescript
@WorkspaceEntity({
standardId: STANDARD_OBJECT_IDS.person,
namePlural: 'people',
labelSingular: 'Person',
labelPlural: 'People',
description: 'A person',
icon: 'IconUser',
})
@WorkspaceIndex(['phone', 'email'])
export class PersonWorkspaceEntity extends BaseWorkspaceEntity {
```
Currently composite fields and relation fields are not handled by
@WorkspaceIndex() and you will need to use this notation instead
```typescript
@WorkspaceIndex(['companyId', 'nameFirstName'])
export class PersonWorkspaceEntity extends BaseWorkspaceEntity {
```

Next step: We might need to implement more complex index expressions,
this is why we have an expression column in IndexMetadata.
What I had in mind for the decorator, still open to discussion
```typescript
@WorkspaceIndex(['nameFirstName', 'nameLastName'], { expression: "$1 || ' ' || $2"})
export class PersonWorkspaceEntity extends BaseWorkspaceEntity {
```
