# Introduction
Initial motivation here was to migrate the object related records logic
from v1 to v2, please note that now in v2 views aren't records anymore
but core engine entities
## What's done
- Added specific label identifier targeting view field logic
- Handled side effects on viewField creation with lowest position on
object label identifier mutation
- Added viewField relations in field metadate entity + handled
optimistic in builder v2
- Added view relations in object metadata entity + handled optimistic in
builder v2
- Added integration tests covering the side effects and new validation
exceptions
- Sandardized cache computation
- Coverage on object metadata creation side effect on views and view
fields
## Coverage
```ts
PASS test/integration/graphql/suites/view/view-field/object-identifier-update-side-effect-on-view-field.integration-spec.ts
View Field Resolver - Successful object metadata identifier update side effect on view field
✓ should create a view field on label identifier object metadata update if it does not exist on view (7 ms)
✓ Should not allow deleting a label identifier view field (17 ms)
✓ Should not allow destroying a label identifier view field (6 ms)
✓ Should not allow updating a label identifier view field visibility to false (8 ms)
✓ Should not allow creating a view field with a position lower than the label idenfitier view field (180 ms)
✓ Should not allow updated labelIdentifier view field with a position higher than existing other view field (346 ms)
✓ Should allow updated labelIdentifier view field with a position higher than existing other view field (434 ms)

# 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
## Introduction
Binding morph relation validation to relation validation code flow
Please note that ALL create field will go through basic atomic
validation, which involve name availability and so on

## Unit testing
I'm not a fan of covering things this way, where we could have some
strong integration testing tests in the first place
But I wanted to freeze the optimistic path computation, also covered the
exception because it was cheap, doesn't mean I won't cover them through
integration tests later anw
