Github user markap14 commented on the issue: https://github.com/apache/nifi/pull/2037 @pvillard31 sorry it's taken me so long to get back to this - it seems to have slipped between the cracks. I did another review and all looks good (except it seems that the description of "Extract Mode" and "Split Mode" were reversed and "Additional Details" confirmed that so i switched it). Did some tests and all works as expected. Definitely a nice addition to the palette! Thanks! +1 merged to master.
