Joseph Witt commented on NIFI-5388:
-----------------------------------
that is a good example of a property i'm not sure you can change dynamically
through the life of a JVM or without having leakage across other instances. I
believe since we have instance isolation for these processors now it is safer
but still will require testing with a couple different usages at once and with
changes.
> Enable EL support for dynamic properties of Kafka processors

> Key: NIFI-5388
> URL: https://issues.apache.org/jira/browse/NIFI-5388
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.7.0
> Reporter: Corey Fritz
> Priority: Minor
> Labels: kafka
>
> We have a flow committed to a NiFi Registry that includes a Kafka consumer,
> and ideally the processor configuration would include some dynamic consumer
> properties where the values would differ depending on which environment the
> flow is deployed to. Unfortunately, dynamic properties in the Kafka
> processors do not currently support EL, which would allow us to use
> environment variables to pass in those environment-specific values. So I'm
> proposing EL support be added to the dynamic properties of all Kafka
> processors.
> I am planning on tackling this ticket myself, unless someone thinks this is a
> bad idea for some reason.
