Subject Re: [DISCUSS] MiNiFi C++ 0.1.0 Release
Date Tue, 22 Nov 2016 20:38:33 GMT
Hi Daniel,

Thanks for mailing and getting involved with MiNiFi!

There is no inherent coupling of versions rather, as has been the custom
within the NiFi community, we use, roughly, semantic versioning.  As a
result, our initial release of MiNiFi C++ started as 0.0.1 and since there
have been some new features, our next release is considered a minor one,
putting us at 0.1.0.  There is no correlation of the C++ version with that
of the Java codebase, rather both being in their relative infancy are
starting from a common place.  Instead, this release is predicated on
keeping a regular cadence of making the community's efforts available for
general consumption.  Additionally, the release is also being suggested as
we've reached a point with the filed issues where those items not scheduled
for the next release require considerable effort and another period of
development to incorporate.

In terms of roadmap, there is nothing rigidly defined and is very much open
to the direction of the community and its will.  There is a rough outline
that was captured on the wiki which I'd imagine you have seen, but is
additionally provided as context for anyone else reading along [1].
Please feel free to share thoughts on specifics in terms of milestones for
challenges you are looking to address on the Wiki and we can look to grow
and evolve that information.

>From my perspective, I feel the most important area is that of chasing down
framework parity with the core features and building blocks of all that our
Java equivalents have to offer.  In addition to this, extending the
flexibility of the user experience in dataflow to our MiNiFi instances as
outlined with some of the feature proposals such as Command & Control
(C2)[2] are areas that can be worked on in a parallel fashion.  In general,
my instincts lead me to believe that the C++ version will be a "generation"
behind Java for the immediate future.  MiNiFi Java allows us to make use of
much of the effort done in NiFi to try new things out, iterate, and expand
functionality quickly.   Once established, we can then perform the same in

In terms of your view of the hub and spoke model, I believe this is the
shared vision of the community long term; the efforts of (C2) would allow
users to more effectively execute such architectures more efficiently,
extending the core principles of NiFi beyond the traditional data center.

We have ensured initial connectivity to core NiFi via the raw socket Site
to Site implementation in C++.  Later, this will be further extended with
the HTTP equivalent, which will make its debut in the MiNiFi realm with the
next release of MiNiFi Java.

Please let us know if there are additional questions you would like to
discuss and appreciate your feedback on the process and look forward to
your continued engagement.
