- Source: [`aws-lambda/lib/schema-registry.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0/packages/aws-cdk-lib/aws-lambda/lib/schema-registry.ts#L139)
- Type last changed: v2.202.0 · 20 Jun 2025

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_lambda as lambda } from 'aws-cdk-lib';

declare const kafkaSchemaValidationAttribute: lambda.KafkaSchemaValidationAttribute;
const kafkaSchemaValidationConfig: lambda.KafkaSchemaValidationConfig = {
  attribute: kafkaSchemaValidationAttribute,
};
```

## Properties

- `attribute`: [KafkaSchemaValidationAttribute](/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.KafkaSchemaValidationAttribute.html) (required) — The attributes you want your schema registry to validate and filter for.

  If you selected JSON as the EventRecordFormat, Lambda also deserializes the selected message attributes.
