## 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
# Morph Relation needs some work on the core API
Especially on the Morph types

# Introduction
Following https://github.com/twentyhq/twenty/pull/13264
> After this PR merge will create a new one removing the type and
replacing it to FieldMetadataEntity.
This is it !
Fixes
https://github.com/twentyhq/core-team-issues/issues/255?issue=twentyhq%7Ccore-team-issues%7C1214.
Until then, in the endpoints of our dynamic schema, we were querying all
columns and then formatting the result by removing the non-requested
fields (fields not mentioned in the graphql Query) from the result.
This is not compatible with field-level permissions that we are about to
introduce because users would see their request denied if they have
restricted rights on any of the fields of the objects they are querying,
even if they did not query it in the first place.
To prepare for this change, we are restricting the list of queried
columns to those made necessary by the graphql query.
I only made the changes in the dynamic schema for now. We will
potentially need to do updates to other part of the app that use
createQueryBuilder directly or not (for instance, when calling
repository methods such as .findOne()), but they mostly regard system
objects that are not subject to permissions or are executed by entities
that bypass permission such as jobs creating People and Companies from
their email sync.
No changes have been brought to existingRecords related logic in the
dynamic schema because @Weiko is currently working on it, so I may need
to adapt the new logic after he is done.
No feature flag have been added so far as this should not change
anything at the moment.
