Subject Re: [DISCUSS] Apache NiFi distribution has grown too large
Date Wed, 17 Jan 2018 16:30:07 GMT
absolutely yes Sumanth - that is what the extension registry would
enable.  There are lots of great discussion points and feedback in
this thread.  I'll try to summarize in a table of pros/cons.  We'll
want to offer a range of these I suspect.

>>> 1. Many decisions, such as the structure of the project/repo(s) and mechanics
of the release, don't have to be made right away, though it is probably good to start considering
the impacts of various approaches as people have. There is a lot that has to be done to make
progress towards the long-term goal regardless of those decisions, some of which follows below.
>>> 2. We can start adding support for extensions to the Registry project (obviously).

belong in the "core" convenience binary and which ones will be published separately. For the
ones published separately, we can further classifying them down into categories / "packs"
to reduce the burden on end-users.
>>> 4. Anticipating that the release cycles of NiFI-core and extensions will eventually
be separated, we should design a way for versioned extensions to declare which versions of
(Mi)NiFi they are compatible with, i.e. as a semantic version range. There are lots of good
examples to pull from; pretty much any modern package management framework has some concept
of support for >=, ==, =~ syntax that honors semantic versioning. If done well, this should
reduce the burden of managing separate release cycles as minor and patch releases of NiFi
will be backwards compatible w.r.t the public APIs used by extensions, so in most cases extensions
declaring a simple 'NiFi >= 1.x' should suffice.
>>> 4b. Likewise, when defining a versioned flow in NiFi, the user should be able
to fix the version of each processor to a specific extension version.
>>> 5. Great work Tony in surfacing some data on NAR size and jar duplication across
NARs. Following up on Bryan's email that explores possible solutions to this, I think the
best approach would be the concept of lib NARs and a more flexible NAR dependency declaration/evaluation
mechanism, e.g., the "mix-in style" Bryan described vs. the current single-class inheritance
style. I'm not sure what work this would require for making the runtime classpaths work correctly.
For just developing/ publishing/installing NARs in this style leveraging an extension registry,
we are getting pretty close to describing a full-fledged package manager, both on the server
side (NiFi Registry) and client side (publishing tooling and NiFi for importing flows that
reference processors that declare dependencies). Given that NAR packs could solve the immediate
problem of reducing the size of individual binaries, I think we should make jar de-duplication
a goal for after a functional extension registry, while keeping it in mind for the design
of the extension registry.
