## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_customerprofiles as customerprofiles } from 'aws-cdk-lib';
const objectTypeKeyProperty: customerprofiles.CfnObjectType.ObjectTypeKeyProperty = {
  fieldNames: ['fieldNames'],
  standardIdentifiers: ['standardIdentifiers'],
};
```

## Properties

- `fieldNames`: string[] — The reference for the key name of the fields map.

- `standardIdentifiers`: string[] — The types of keys that a ProfileObject can have.

  Each ProfileObject can have only 1 UNIQUE key but multiple PROFILE keys. PROFILE means that this key can be used to tie an object to a PROFILE. UNIQUE means that it can be used to uniquely identify an object. If a key a is marked as SECONDARY, it will be used to search for profiles after all other PROFILE keys have been searched. A LOOKUP_ONLY key is only used to match a profile but is not persisted to be used for searching of the profile. A NEW_ONLY key is only used if the profile does not already exist before the object is ingested, otherwise it is only used for matching objects to profiles.
