Joseph Witt commented on NIFI-4024:
-----------------------------------

Yeah that is true.  I'm not sure how that would work though in the case of 
partitioning.  With split it makes sense since we're just taking sequential 
chunks.  With partition we're not doing that so i'm not sure fragment tracking 
would really work.  We do need to provide a MergeRecord processor though!

> With the new RecordPath DSL, it would be nice if there was a processor that 
> could pull fields into attributes of the flowfile based on a RecordPath. This 
> would be similar to the EvaluateJsonPath processor that currently exists, 
> except it could be used to pull fields from arbitrary record formats. My 
> current use case for it would be pulling fields out of Avro records while 
> skipping the steps of having to convert Avro to JSON, evaluate JsonPath, and 
> then converting back to Avro.
