Hi, We have a NiFi cluster which spans two physical locations, Zone A and Zone B.  We are clustering across locations for ease of management.  In each location we have hosts running NiFi acting as data collectors, enriching the data and then sending to the main cluster via site-2-site (using remote processing groups). My question is: We want data originating in Zone 1 to only hit the NiFi Cluster nodes in Zone 1.  Using site-2-site, even if we only configure the Zone 1 nodes in the RPG, NiFi will report the presence of the Zone 2 nodes hence data originating from Zone 1 will cross the WAN and end up in Zone 2.  Does NiFi have any concept of zones? We currently achieve this by configuring a firewall rule to block outgoing traffic to Zone 1 nodes from Zone 2 (and vice-versa), but this produces warnings in the RPG. Any thoughts or ideas would be appreciated.  Thanks  ... View more
