It all depends on how does the remote device report the models. It is possible if a remote device reports yang model with 2 different revisions but for get-schema it returns the same yang file. Netconf connector has to download both of them since it does not know what the content would be.

So it is expected if the device reports the models that way. This should be verified in your netconf device because I dont think there is any issue in ODL's netconf connector.

Please verify with your device and close this issue.

I think the problem may be on the NE, which does not advertise the model revision – which is not exactly a conformance issue, as both naming conventions are allowed.

Since the revision is not advertised, the schema repository does not know the revision of the model until it parses it – but to do that it needs to download it first, which triggers a writeout.

This problem can actually be larger, as we should somehow enforce the consistency of the file name and the module/revision statements contained in it. That means that the cache should only be populated once the model has been parsed successfully.

Giles, is this still happening?

I think this got fixed along with YANGTOOLS-769 – I will close it for now, feel free to reopen if you encounter it again.
