Considerations

Parameters Directory

The parameters directory in this project is intended to provide an example of being able to "hot-reload" parameter values. In a real scenario, this directory would not be committed to git (or you would at least not commit files with sensitive information).

TODOs

More Automated Setup

Some of the setup steps could in theory be automated, but I don't feel like doing that work currently.

• Parameter Providers
  • I'm pretty sure this can be automated, but I can't find an API doc for this part.

Known Issues

This guide can't be used with 2.0.0-M1 because of NIFI-12531. You must wait until 2.0.0-M2, which contains the fix for this issue.
