> Add Variable Registry at Process Group level
> --------------------------------------------
>
> Key: NIFI-4224
> URL: https://issues.apache.org/jira/browse/NIFI-4224
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
>
> Currently, NiFi exposes a variable registry that is configurable by adding
> the name of a properties file to nifi.properties and then treating the
> referenced properties file as key/value pairs for the variable registry.
> This, however, is very limiting, as it provides a global scope for all
> variables, and it requires a restart of NiFi in order to pick up any updates
> to the file. We should expose a Process Group-level Variable Registry.
