- Source: Generated code
- Type last changed: v2.93.0 · 23 Aug 2023

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_cleanrooms as cleanrooms } from 'aws-cdk-lib';
const dataEncryptionMetadataProperty: cleanrooms.CfnCollaboration.DataEncryptionMetadataProperty = {
  allowCleartext: false,
  allowDuplicates: false,
  allowJoinsOnColumnsWithDifferentNames: false,
  preserveNulls: false,
};
```

## Properties

- `allowCleartext`: boolean | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) (required) — Indicates whether encrypted tables can contain cleartext data ( `TRUE` ) or are to cryptographically process every column ( `FALSE` ).

- `allowDuplicates`: boolean | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) (required) — Indicates whether Fingerprint columns can contain duplicate entries ( `TRUE` ) or are to contain only non-repeated values ( `FALSE` ).

- `allowJoinsOnColumnsWithDifferentNames`: boolean | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) (required) — Indicates whether Fingerprint columns can be joined on any other Fingerprint column with a different name ( `TRUE` ) or can only be joined on Fingerprint columns of the same name ( `FALSE` ).

- `preserveNulls`: boolean | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) (required) — Indicates whether NULL values are to be copied as NULL to encrypted tables ( `TRUE` ) or cryptographically processed ( `FALSE` ).
