i love this presentation, could u please give more explanation regarding creation of custom processor and NAR file.

I tried to connect two GenerateFlowFile processors to a single PutFile processor without a Funnel. I connected them directly and it worked fine. It also works if I connect them using a funnel. So when exactly should we use a funnel? Could you please explain.

I'm missing the point, why to use a funnel. I understand that you can't connect output to input ports. But (at 3:00) why not just connect the two GenerateFlowFile-Outputs directly to the Log-Attribute? You don't need a funnel for that.
I think there are three purposes for using a funnel:
a) for changes: if you funnel MANY connections to one destination-processor, and you want to exchange the destination-processor, than you only have to draw one new connection - and not all the connections from all the source processors. (Same if you funnel one source to many destinations - then you can easy exchange the source-processor, because it has only one connection to the funnel).
b) prioritize queues: if you connect many processors to a funnel an then connect the funnel (for the combines queue) to one destination-processor, you can define prioritize-settings for the combined queue. (I think this is the most importent reason for funnels.)
c) possibly for controlling backpressure: by having the single queues and separate a combined queue, this has impact of the backpressure behaviour.
