## Put a record to a Kinesis Data Firehose

Use the `KinesisDataFirehosePutRecord` target to put a record to a Kinesis Data Firehose delivery stream.

The code snippet below creates an event rule with a delivery stream as a target
called every hour by Event Bridge Scheduler with a custom payload.

```ts
import * as firehose from 'aws-cdk-lib/aws-kinesisfirehose';
declare const deliveryStream: firehose.CfnDeliveryStream;

const payload = {
Data: "record",
};

new Schedule(this, 'Schedule', {
schedule: ScheduleExpression.rate(Duration.minutes(60)),
target: new targets.KinesisDataFirehosePutRecord(deliveryStream, {
input: ScheduleTargetInput.fromObject(payload),
}),
});
```
