Firenz updated NIFI-7596:
-------------------------
    Description: 
*Use case :* the flow file contains 1 big data (ex : PDF or pictures), but you 
want to lookup metadata with InvokeHTTP using a POST (or PUT). POST is often 
used in http API for "search" with lot of params or list of params.

Other exemple is the 3-steps batch-upload of products like Nuxeo or Salesforce 
Bulk API : you need to "open" a batch with a POTS invokeHTTP.

 

*Proposition* : In the InvokeHTTP, add a "Get Request Body From Attribute" 
(like Put Response Body In Attribute). If this field not empty, the chosen 
attribute will be read as the request, insted of the flow file.
