Github user ijokarumawak commented on the issue: https://github.com/apache/nifi/pull/2686 @mans2singh As long as we can construct useful flow with these components, I am ok on how to do that. By using correlation id, we can merge original FlowFile to the prediction result. However I assume we need to write a custom code with ScriptedProcessor to do something from there, if we want to do something within a NiFi flow. Would you be able to provide a flow template featuring the processor with input dataset to illustrate how correlation ids helps merging prediction result to the original dataset?
