Hi,
I tried to get a couple companies interested in this draft but it did not
really work for them.
There is low demand for an NMDA diff but high demand for a more general
"YANG data compare" operation.
The main issues raised were:
1) can only compare 2 datastores
Want to compare a datastore to a backup (or more generally a URI, ala
copy-config)
2) The output is only YANG Patch
Want a "config" container that can be used with the "edit-config"
operation.
NETCONF clients cannot use the YANG patch format to edit a datastore
with the differences
3) Not interested in the complex filtering and "origin" attributes
Not applicable to the use-case.
The main use-case:
1) make a backup of a server (or already have a common baseline shared
across servers)
2) make config changes to the server and test them out
3) get a diff that can be used as a "patch" to the backup
4) apply the patch to different servers (that are running a compatible
config as the backup or baseline)
I realize there are no standard "backup" and "restore" operations so I am
not suggesting
that the draft be redone to support this use-case.
