David Handermann commented on NIFI-14841:
-----------------------------------------
Thanks for raising this concern [~praveendharam]. Can you provide some
additional details about the flow design and expected distribution. Details
such as expected attribute cardinality and number of nodes would be informative.
Changes in NiFi 2.3.0 for NIFI-14236 corrected some poor distribution that was
occurring since NiFi 1.16.0. However, if there are additional issues, it would
be helpful to track those down. Any details that could support reproducing the
problem would be useful.
> In NiFi 2.4, the load distribution is uneven, whereas it worked correctly in
> NiFi 2.0

> URL: https://issues.apache.org/jira/browse/NIFI-14841
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Praveen Dharam
> Priority: Major
>
> In NiFi 2.4, we are experiencing uneven load distribution across nodes when
> the load balancing strategy is set to Partition by Attribute.
> The primary issue is that the majority of the load is being routed to a
> single node out of the three in the cluster.
> This imbalance has significantly reduced our throughput during volume
> testing—an issue that was not present in NiFi 2.0.
