I think we can remove ATTRIBUTE_KEY_PROPERTY_NAME_VALIDATOR. The dynamic
properties of this processor are not representing FlowFile attribute names. It
is a little bit misleading.
> Add lookup processor for enrichments/joins to reference data

> 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.
