Hi,

I hope this work gets high priority.
There are many I-Ds already so please do not start over or greatly expand
the scope.
I have been saying that YANG Push is too complicated since I was on the DT
that created RFC 8639,40,41.

We have a fairly complete implementation of dynamic subscriptions.
Glad to see there is now consensus to get rid of the YANG Patch update.
We decided the same thing a long time ago:
https://docs.yumaworks.com/en/latest/cli/netconfd-pro.html#push-simop-patch-update

Also agree that a push update is not a full replace, but rather just
gather what is being reported.  That is also how our server works.

I do not understand the issue with dampening.
Within the implementation, it means how often you check for changes.
It is effectively the same as the 'period' for a periodic subscription.
How does an on-change subscription work without this parameter?


Andy
