When creating a Stream, specify the DataSet properties (name and description) and as a convenience, the create Stream API will create a DataSet for you.
Streams support both append and replace import methods, as well as Upsert. In order to create an Upsert dataset you must specify the Upsert key column(s) in keyColumnNames and set updateMethod to APPEND.
Limitation
The StreamAPI currently only allows you to import data to a DataSet created via the Stream API. For example, it is currently not supported to import data to a DataSet created by a Domo Connector.
