Transferring data from AWS Kinesis data streams to AWS Redshift using AWS Glue

With Redshift Streaming Ingestion, you can now directly consume data from Kinesis Data Streams from within your Redshift Cluster without needing to ETL through Glue Streaming. Is Glue mandatory or can you use this feature?

The feature is in Public Preview however and is expected to GA soon this year.
