Great info Bryan- thanks! Regarding my first question, I talked to our admins and we only have one NIC anyway. So there is no need for me to limit it, and thus I don't have a need to use EL to discover the NIC. So that's good.
Regarding the registry stuff, I found this [1] document which looks FANTASTIC. But I'm not able to find when/if this stuff will be released. My understanding is that it is not yet released, and therefore I'm assuming that specifying a custom.properties file via the nifi.variable.registry.properties is still the preferred method. Additionally, this will mean that: 1) Changes to this file require a service restart, correct? 2) Is it true that this needs to be specified for each node of a clustered environment? Thanks again!
