Hello,
having reviewed the proposal, I am not quite clear of points here:
- DataTreeChangeService paragraph seems to imply DataTreeChangeService
API contract is not being correctly implemented
- since the feature is integrated at DOMDataBroker level (as opposed at
DOMDataTreeService level), it is not clear how this would work in a
hybrid environment -- I don't quite see where inter-datastore
compatibility is solved. Most notably, it seems that RESTCONF is singled
out as 'special' and has a proxy injected, yet other applications use
specific datastores. How would a mix of CDS/Yongo/etcd-using
applications work and how does this relate to the MD-SAL APIs?
- project scope is a bit blurry. Can we get a clear, bullet-point list
of what the project is all about? The sentence 'For Restconf, it
requires users to rebuild 'restconf-nb-bierman02' and
'restconf-nb-rfc8040' to reference to DOMDataBroker and
DOMDataTreeChangeService with a new type.' feels like a hack, not like a
properly-architected solution. This leads me to believe the project does
not really integrate, as it does a whole-sale replacement of a single
implementation. This is going to a nightmare from packaging perspective,
at the very least.
- the proposal spells DOMRpcService, but does not mention
DOMActionService. RFC7950 makes a rather strong connection between the
operational store and DOMActionService -- what are the interactions
between these?
- what does the 'alt-ds-adapter' do? how does it relate to existing
MD-SAL interface?
- a flow diagram showing interactions between one application using etcd
and another using yongo, is definitely needed. Unless the proposal is to
have such applications live in isolated worlds -- in which case it needs
to be explictly spelled out.
The project proposal has underwent rapid expansion in the few weeks it's
been out and I feel the problem domain is still being explored -- there
are architectural questions which seem to be far from having been
considered, let alone having concrete questions.
I would therefore ask for the review period to be extended, so the
proposal can be fleshed out, especially its interactions with MD-SAL
APIs, packaging and migration point of view.
Note: I am not asking for them to be completely resolved, but rather for
the problems to be acknowledged and a rough outline of a solution to be
brought into the scope of the project or an explicit exclusion added.
Thanks,
Robert

This Monday-Tuesday we have the DDF. Maybe Jie and you can do a remote

avoid late Tuesday afternoon Pacific time as some ONS related activities
start).

*Abhijit's** answer:*
In the past, the TSC has offered projects in other timezones to skip
presenting about the project and for the TSC to vote. In this case it
certainly makes sense. However there has to be a two week review period
(as per the creation review process) - which in this case would be March
21st to April 3. I will initiate a vote on April 3.

I just realized that I won't be able to attend the TSC
meeting on April 11th (due to school vacation starting here
that Friday and related personal plans).
If the agenda on today's TSC call is not overly full
already, perhaps we could discuss this project proposal today?

During the review period, discussion and

*主 题 ：Re: Propose a new project:
Alt-datastores*
Jie, Michael and folks,
You have submitted the project proposal
today March 21. The next steps would be to
have the creation review for the project in
a TSC meeting after a two week review
period. Ordinarily two weeks would have
placed the review in the April 4th TSC
meeting. Since several of us will be at the
ONS, North America on that date and will
also be meeting in person at the
OpenDaylight DDF on April 1-2, we will
likely cancel that week's meeting. Hence, it
makes sense to have the review in the TSC
meeting on April 11.
Would it be possible for you folks to attend
that meeting? Logistics (web
conference/dial-in) of the TSC meetings are
at: https://wiki.opendaylight.org/view/TSC:Meeting.
Thanks,
Abhijit

Dear Abhijit and all,
I together with Michael Vorburger and
team members from China Mobile and China
Telecom want to propose a new project in
ODL called Alt-datastores.
The topic of this project has alaways
been discussed in the past. ODL will be
able to support a 3rd-party datastore
with our project.
The details is as the proposal shown:
https://wiki.opendaylight.org/view/Project_Proposals:Alt-datastores
Please let me know what should I do next.
