 | queue_arn       | The ARN of the SQS queue, which triggers the Lambda function. Must be defined if 'stream_arn' is not defined.              | `string` | null    |    no    |
-| stream_arn      | The ARN of the DynamoDB stream, which triggers the Lambda function. Must be defined if 'queue_arn' is not defined.         | `string` | null    |    no    |
 | batch_size      | Amount of items a single Lambda invocation processes from the source.                                                      | `number` | 1       |    no    |
