Joseph Witt commented on NIFI-2379:
-----------------------------------
Right now as it is site-to-site offers load balancing and fail-over between any
two sites (source site and destination site).
This JIRA is to extend its function to support a given source site with one or
more destination sites for fail-over and possibly load balancing.
The complicated part of this concept is 'when to fail-over' to the other
cluster. One might want this to be 'if failure occurs to all nodes in a given
site THEN fail-over to the other site". Another person might want 'as soon as
failures occur to any nodes within the cluster begin some level of alternate
routing. A related consideration is when to start going back to the preferred
site. The preferred site concept means we have to possibly enable
prioritization of sites. This same sort of thought process probably also makes
sense for load-balancing as well.
