Matt Burgess commented on NIFI-7724:
------------------------------------

How do you envision this working with the cache? Would it return a one-field 
record containing a String representation of the value in the cache? Or do you 
mean adding a RecordReader property so you could store multiple fields in the 
cache value (as a JSON string for example) and retrieve them all as a Record? 
The first option is straightforward and would just give you access to the cache 
from a processor that requires a RecordLookupService, the second is more 
complex but more flexible.
