title: use output of azure function is azure data factory
body: <p>There is a possibility to use an Azure function immediatelly in Azure Data Factory and you can send parameters to the Azure function as inputs. But now I want to use the output of my Azure function immediatelly in my Azure Data Factory. Is this possible or do I need to save the result of my Azure function in a database/blob?
  With the Azure function, I'm doing some manipulation on data and after that, I need to join the result of the Azure function with some data of another database. I would prefer to join both data sets directly in Azure Data Factory instead of in the Azure function for readability reasons</p>
