all

Start by locating the Kinesis Firehose L2 Construct in the aws-cdk repository and compare its delivery stream configuration with the linked CloudFormation IcebergDestinationConfiguration reference. Add support for the Iceberg destination settings, then verify the construct synthesizes the expected CloudFormation configuration and that relevant tests pass.
