Working asynchronously with REST on KNIME Server

Hey,

according to https://www.knime.com/blog/giving-the-knime-server-a-rest
Jobs can be executed asynchronously.
Can a workflow be executed directly asynchronously without creating a job first?
Can files from KNIME Server be retrieved asynchronously?

Thanks!

For completeness of record I’m adding results form our side conversation:

Neither async execution nore async download is possible. For async execution of a job, one needs to create a job first, which can only be done synchronously.
