Andre F de Miranda commented on NIFI-542:
-----------------------------------------

[~markap14] I appreciate the value of the functionality but given the blurb in this JIRA seems to be referring to 0.x I was wondering: Would you say this is still applicable considering we now rely on ZK?

> Currently there exists a master/slave paradigm. If the NCM has to orchestrate the flow across many, perhaps geographically dispersed, nodes, we don't want to replicate every request to many nodes. It would be better to send a single request from a "higher-level NCM" to several "lower-level NCMs" and have the lower-level NCM's replicate to the nodes.
