Subject Re: Managing flows

Mark,
    Thanks for the tips. Appreciate it.

So when I run nifi on a single server. It is essentially "one flow"?
If I wanted to have say 2 or 3 active flows, I would (reasonably) have 
to run more instances of nifi with appropriate
configuration to not conflict. Is that right?
