Brian,
I would encourage you to create a JIRA ticket with these ideas.
They are good ideas that we don't want to lose.
As far as allowing pluggable functions, that's likely a pretty big task
and not likely to have too soon. But these functions could be
implemented much sooner than that, I would imagine.
Thanks

Also, we'd like to be able to format a timestamp (number) into a
particular
timezone regardless of the timezone set on the host. Since NiFi uses
SimpleDateFormat, that's exposed programmatically via
sdf.setTimeZone(...).

Thanks! A few options for extension language enhancements I can think
of
off-hand are:
- Capitalize
- Pretty Date ( e.g., "yesterday", "an hour ago", "a few seconds
ago" )
- Phone Formatter
- IP v4 and v6 Formatters
While a few of those can be done with some chaining of the existing
methods, it would be much nicer to handle more cleanly.

it being open source means it is extensible.
It as a functional area not designed for extension means it will be
less fun to do so. Definitely sounds like something worth thinking
through how it can be done.
