# Introduction
Created the runner metadata for the field and object
We should keep in mind that any runner handler will only iterate over an
atomic instance of entity ( object field index etc )
Never triggerring any side effect or whats over
In this way we will need to implement a deferred transaction, as for
when we create a relation we will inject to the first created field of
both the `relationTargetFieldMetadataId` deterministically computed
before its own creation
This would result in pg constraint brokage if not deferred
## Updates
- We decided gather create_fields under the create_object as they will
be building within the same sql query. This will ease both generation
and computation and avoid disassembling to reassemble afterwards
- Refactored FlatFieldMetadata to handle relation typing with flat
occurences
```ts
runCreateFieldSchemaMigration = async ({
action,
queryRunner,
}: WorkspaceMigrationActionRunnerArgs<CreateFieldAction>) => {
if (isFlatFieldMetadataEntityOfType(action.flatFieldMetadata, FieldMetadataType.RELATION)) {
action.flatFieldMetadata.flatRelationTargetObjectMetadata
}else {
action.flatFieldMetadata.flatRelationTargetObjectMetadata // tsc-error never
}
return;
};
```
## TODO
- ~~Discuss action signature with @Weiko in order to anticipate `schema`
runner needed grain~~
- ~~Refactor the object actions to contain picked `flatObjectMetadata`~~
- Implem index service

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
