I don't see the simple way of doing this. The part I see complicated is
registering static properties in a custom processor, so we should rely on
dynamic ones, however those require evaluation in every trigger by their
nature.
How would you do this?
> C API: provide functions to create custom processors

> Project: NiFi MiNiFi C++

> Reporter: Arpad Boda
> Assignee: Arpad Boda
> Priority: Major
> Labels: CAPI, nanofi
> Fix For: 0.6.0
>
>
> Extend C API to:
> -Provide functions that can be used used to implement custom processor.
> -Custom processor should be able to read/update both the content and the
> attributes of flowfile, route to "failure" and "success" relationships.
> -API should support adding these custom processors to flows and invoke them
> as standalones, too.
