@jfrazee @mattyb149 I reviewed the updated commit and found few points to
improve.
I was trying to comment all of those, but since it's easier to explain with
code instead of comment, I created another PR based on this one.
@jfrazee Would you take a look on #1856 to see if those changes are
reasonable? Please find the [commit
comments](https://github.com/apache/nifi/pull/1856/commits/4f81af0961c3d65c4df37b9de3934c8fed1a70ff)
for what I've changed. If my additional commit looks ok, then I'd give +1 to
this PR.
> Add lookup processor for enrichments/joins to reference data
> ------------------------------------------------------------

> Key: NIFI-3404
> URL: https://issues.apache.org/jira/browse/NIFI-3404
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joey Frazee
> Assignee: Joey Frazee
>
> NiFi doesn't currently have an easy, concise way of doing enrichment, joining
> against reference data sets or performing attribute lookups against external
> data sources.
> Since enrichments and joins are basic streaming use cases, and since
> attributes and EL are often used to parameterize processor properties, there
> is a need for an easy way to do enrichments, joins and lookups without having
> to write code or create a lengthy data flow.
> There's been some discussion of this on the mailing list [1] and I've started
> work on a LookupAttribute [2] processor that delegates the work to controller
> services.
