title: Is it possible to specify data format conversion in AWS Cloudformation?
body: <p>The AWS docs makes it look as if you can specify <code>DataFormatConversionConfiguration</code> for a <code>AWS::KinesisFirehose::DeliveryStream</code> in cloudformation, but is not documentation on where the property is supposed to go. Tried adding it under <code>Properties</code>, <code>ExtendedS3DestinationConfiguration</code>, <code>ProcessingConfiguration</code>, and one of the <code>Processors</code>. Each time, CF complains with-</p>
  
  <blockquote>
    <p>The following resource(s) failed to update: [EventFirehose].
    12:24:32 UTC-0500</p>
    
    <p>UPDATE_FAILED AWS::KinesisFirehose::DeliveryStream    EventFirehose   Encountered unsupported property DataFormatConversionConfiguration</p>
  </blockquote>
  
  <p>There own docs say-</p>
  
  <blockquote>
    <p>If you want Kinesis Data Firehose to convert the format of your input data from JSON to Parquet or ORC, specify the optional DataFormatConversionConfiguration element in ExtendedS3DestinationConfiguration or in ExtendedS3DestinationUpdate.</p>
