Zenkovac updated NIFI-14864:
----------------------------
    Description: 
switching from nifi 1.19 to 2.5 and using ConsumeKafka cant get to consume 
flowfiles with more than ~500 records per flowfile despite having millions of 
messages available in kafka topic each flowfile

This has a penalty performance for me because I consume thousands of flowfiles 
vs a few in nifi 1.19 hich means less disc i/o usage.
this is my config:
*Processing Strategy: RECORD*
*Max Uncommitted Time* 10 sec
