How to enable Kinesis Firehose new line delimiter via CloudFormation?

Question

There is a relatively new feature for Firehose to append new line at the end of records before saving them to S3: https://docs.aws.amazon.com/firehose/latest/dev/create-destination.html

by enabling "new line delimiter" option. I can see this option in the console, but I cannot see anything mentioned about it in the KinesisFirehose CF documentations:
* https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-extendeds3destinationconfiguration.html
* https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-kinesisfirehose-deliverystream.html#cfn-kinesisfirehose-deliverystream-extendeds3destinationconfiguration

Is it possible to enable the "new line delimiter" option via CloudFormation? If yes, then how?

Accepted Answer

The new line delimiter configuration is a type under the Processing Configuration within your Cloud Formation Template for your S3 Destination.

For JSON this will look like:

{
                    "Type": "AppendDelimiterToRecord",
                    "Parameters": [
                        {
                        "ParameterName": "Delimiter",
                        "ParameterValue": "\n"
                      }
                    ]

For the YAML this will look like:

- Type: AppendDelimiterToRecord
            Parameters:
            - ParameterName: Delimiter
              ParameterValue: "\n"

For a more detailed example of how this should look from a higher level within your template, please refer to the documentation [1] below:
