@joetrite it would be good to get a clean master, create a branch, put your
changes on it, then submit that PR. This one has a couple merge commits now
and they're probably not needed (rebase would likely have done the trick). Can
you clean up the commit history for this PR? Definitely appreciate the work
you're putting in and don't want to put you through hoops but would like to
keep the commit clean.
> ScanAttribute should support tagging a flowfile with metadata value from the

> Today ScanAttribute just looks through the supplied dictionary and given
> object for a string matching hit. If it hits then it is a match otherwise it
> is a 'not found'. However, when a hit occurs it can often be quite useful to
> gather additional metadata about that hit. This makes cases like
> enrichment/tagging much easier.
> So, plan is to have ScanAttribute support a dictionary value demarcator which
> would separate the dictionary term from some string response that will be
> added to the flowfile. For instance a dictionary might have
> apples:These are red or green
> bananas:These are yellow unless you should toss them or make bread
> Then if a hit occurs on 'apples' the flowfile that contained such an
> attribute would have a new attribute such as 'dictionary.hit.term' = 'apple'
> and 'dictionary.hit.metadata' = 'These are red or green'.
> This means downstream processors could extract that metadata and do
> interesting things with it.
