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
