主题: [lists.opendaylight.org代发][OpenDaylight TSC] TSC Attention: New project proposal discussion at DDF Tues 9 am Pacific: Alt-datastores

 

Hi TSC members and others,

 

Please note that the Alt-Datastore project proposal has been out for review since March 21: https://wiki.opendaylight.org/view/Project_Proposals:Alt-datastores

 

We will be having a discussion where the project proposers will be explaining the project tomorrow at the DDF - as well as have an opportunity for the TSC and others to ask questions to the proposed project team before the TSC members can vote. Please attend. You can attend remotely if you cannot attend in-person. The logistics of dialing in are at: https://wiki.opendaylight.org/view/Events:Sodium_Dev_Forum#Logistics.

 

Basically:

 

9 am Pacific on Tuesday April 2, 2019

 

Thanks,

Abhijit

To avoid confusion and to have more notice to the TSC members - let us have this as the first session during the DDF tomorrow. I will send out the email to TSC after talking with Casey at the DDF - so that the TSC members will be present tomorrow for that session.

Jie and I would be willing to remotely join the DDF on https://zoom.us/j/265964615 to answer any Qs re. https://wiki.opendaylight.org/view/Project_Proposals:Alt-datastores.

 

We just checked the time zones and realized that for Jie in Beijing it's midnight when you start over there in California... is there any chance that you could squeeze this discussion in at the start? I shouldn't be very long (from our end). Looking at https://wiki.opendaylight.org/view/Events:Sodium_Dev_Forum I can see a packed schedule (great!), so we appreciate the flexibility, if it's possible.

 

Me and Jie will dial in on Zoom today, just to be available. If this is too late notice for today (sorry), then I suggest at the start (PST 9am) tomorrow as fallback.

 

Tx,

M.

Scope paragraph has been updated:

Scope
1. Alt-datastores would inlude adapters of 3rd-party datastores, one adapter like Yongo should at least have ability of saving binding/normorlized data to a 3rd-party datastore;
2. Alt-datastores would replace CDS to provide the default DOMDataBroker serivce that is transparent to other components.
3. Multiple adatpers could be applied for repica data perpose.

主题:Re: [OpenDaylight TSC][lists.opendaylight.org代发]Re: Propose a new project: Alt-datastores

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
