Hi @Andrew Grande I am trying to download a template using rest api - where do I get the id of the template /templates/{id}/download I have stored the template with a name. Thanks, Avijeet ... View more

Thanks @Bryan Bende, makes sense. quick follow up. So can we say we can have one cluster (say 5 node) - we can put the nifi + KAFKA (one broker in each node) in same nodes, I believe HDF cluster would be doing same way, so each node would have a nifi instance + KAFKA broker + storm supervisor. Also as NIFI doesn't do replication, it would not be disk crash proof. please correct if wrong. ... View more

Hi @Bryan Bende Great Artcile! I have one question - KAFKA is a disk-bound distributed system I believe NIFI as well disk bound as it acts a reliable-buffer similar to KAFKA + all the productivity ui based Is there a strong reason to go for both NIFI + KAFKA what are the reliability features of NIFI, is it machine/disk crash proof? The persistent/replay features of KAFKA are mostly not there in NIFI? pls correct me if wrong. ... View more
