Hey @patricker - I'd need to revisit the PR to add some minor things like
EL scope and similar things. Regarding the processor itself, I believe it adds
some interesting possibilities and still think it could be an interesting
addition. However, I want to be sure the concerns raised in the JIRA are
addressed before moving on. If people are interested by this feature, feel free
to drop a comment on the JIRA: https://issues.apache.org/jira/browse/NIFI-4200
