Zenkovac commented on NIFI-14864:
---------------------------------
tried setting those values to 1 or 10MB but still the same.
I can see from logs that those values are ok by default:
fetch.max.bytes = 52428800
max.partition.fetch.bytes = 1048576
i'll see if i can spin up a kafka 3 server to test performance.

> Key: NIFI-14864
> URL: https://issues.apache.org/jira/browse/NIFI-14864
> Project: Apache NiFi
> Issue Type: Bug
> Components: Configuration
> Affects Versions: 2.5.0
> Environment: nifi 2.5, kafka server 2.8
> Reporter: Zenkovac
> Priority: Major
>
> 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.
> This has a penalty performance for me because I consume thousands of
> flowfiles vs a few in nifi 1.19 which means less disc i/o usage.
> this is my config:
> *Processing Strategy: RECORD*
> *Max Uncommitted Time* 10 sec
