title: Use Apache Superset API to feed a dataset
body: <p>I would like to understand if this is possible to populate a Superset dataset using the Superset API.
  I browsed the <a href="https://superset.apache.org/docs/rest-api" rel="nofollow noreferrer">documentation</a> and I have the feeling that we can't do it the way we upload a CSV file for example.
  I know the other possiblitiy is to directly write in the database but I find APIs more secure and also more easy to use and maintain.</p>
