> The contribution for NIFI-3404 was originally intended to include a DatabaseLookupService, but due to various reasons it was excluded from the final PR that was merged.
> This Jira proposes to add a DatabaseLookupService controller service, where values can be retrieved from an external RDBMS (through the use of a DBCPService). Design considerations include which key(s) to accept, whether to locally cache no/some/all queries, result sets, etc. The major requirement is to be able to enrich record-based flow file values (via LookupRecord) from an external RDBMS source.
