Hi, I'm a newbie to nifi and i have a scenario where consume kafka record processor fetches 10 million records(not in a single queue/flowfile). The consume kafka records processor runs for a certain amount of time.I need to merge all these flowfiles  into a single flowfile. The problem is , when the processor first runs, it fetches few flowfiles and these flowfiles need to be held until the same processor finishes running and gets the remaining flowfiles.
