Joseph Witt commented on NIFI-1571:
-----------------------------------
Some future thoughts:
- Would be good to document/understand the memory usage/implications.
Obviously we're floating between worlds here and there will be some memory copy
things. We should explain those.
- Would be amazing if we can get provenance working through these flows somehow.
> Provide generic processor that would bootstrap itself from Spring's
> Application Context

> So, several clients have expressed interests in using WorkFlow orchestration
> frameworks such as Camel, Spring Integration etc. to be able to encapsulate
> yet modularize and externalize the complexity of some of the custom
> processors as well as handle some of the use cases that fall outside of scope
> of Data Flow paradigm (e.g., transactional context and XA between two+
> Processors).
> There is already a ticket to provide Camel support - NIFI-924. However
> realizing that both Camel and naturally Spring Integration is based on Spring
> Application Context it appears that instead of having multiple extensions we
> should have a more generic extension for a Processor that would delegate its
> processing to a bean in provided Spring Application Context (AC). This way AC
> becomes a black box and could contain anything (e.g., Camel, Spring
> Integration or some custom user code).
