Some job estimates may not be possible, e.g. for a UDF. For UDFs a back-end may not be able to give an estimate as the code is not really known/understood by the back-end automatically. Thus, we should clarify in the API how a back-end should reject estimates in such cases (e.g. a specific error code via HTTP 400)
