Bryan Rosander commented on MINIFI-36:
--------------------------------------
Once NIFI-1820 is implemented, these pull semantics might be able to be
implemented via an extension to the Site To Site protocol. This would
hopefully allow the same channel(s) used for sending data to the NiFi cluster
to be used to be notified of configuration changes.

> Key: MINIFI-36
> URL: https://issues.apache.org/jira/browse/MINIFI-36
> Project: Apache NiFi MiNiFi
> Issue Type: Improvement
> Components: Processing Configuration
> Reporter: Aldrin Piri
> Fix For: 0.1.0

> Much like the efforts of MINIFI-12, it would also be convenient for a
> configuration in which an instance could reach out to a defined endpoint to
> poll for changes and bring those into the associated bootstrap process to
> activate a change in processing.
> Considerations include the mechanism in which polling occurs and how this is
> exposed. A way of knowing if the flow is new, likely bound to the efforts of
> MINIFI-35. In one case, it is conceivable that an instance could reach out
> to a NiFi instance and its associated API to receive configuration.
