Joey Frazee commented on NIFI-3946:
-----------------------------------
[~joewitt] Is the suggestion to allow multiple lookups simultaneously or to do
lookups with multiple constraints such that the map is basically like the
conjunction of conditions in a WHERE clause? If it's the latter then won't you
box out the case where you're using individual dynamic properties to do several
lookups? Both seem like valid approaches so it might make sense to just have a
flag that says which mode it's in rather than only do multi criteria lookups
(if I've understood it correctly even).
> Should update LookupRecord to allow multi criteria lookups

> At present the LookupRecord processor allows a single criteria lookup.
> We need to provide a lookup API which takes a map of string key/values that a
> given lookup can use when searching for the result. The LookupRecord
> processor should change such that all dynamic properties are the loookup key
> names with values that are the RecordPath to find the value for that given
> key. The resulting map would be passed to the lookup service. Also the lookup
> service API should allow returning the set of required key names so that the
> processor can validate once all required keys have RecordPaths to search for
> values.
