Joseph Witt commented on NIFI-5083:
-----------------------------------
[~rbruno] does this mean you're using the FlowRegistry to ensure both clusters
have a consistent flow and thus are ending up with the same group id being used?
Adding support for EL to let variables be used is a very doable option and a
good idea. Just wanted to understand how you're keeping the flows so in sync
between clusters that this would be matching at this time.
Thanks

> Key: NIFI-5083
> URL: https://issues.apache.org/jira/browse/NIFI-5083
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.6.0
> Reporter: Robert Bruno
> Priority: Minor
> Labels: kafka
>
> I have the use case where I have two separate NiFi clusters reading data from
> the same topics but need to have unique group ids so they each get separate
> copies of the data. It would be useful if the group id field supported
> expression language so I could use a processor group variable to define the
> group id to use. I have a large enough number of kafka consumers to make
> this tedious to manually change.
