Hi,

I have a few questions. inline.

What is meant by the "native" clients here? Can you give an example?


A]  READ path needs to be changed :

If native client can get all the info through the rest-endpoint-k8s
handler, why in case of magnum client do we need to go through rest-api->
conductor? Do we parse or modify the k8s-api data before responding to the
python-magnum client?

If we completely bypass the conductor, is there any way to keep a track of
trace of how a resource was modified? Since I presume now magnum doesn't
have that info, since we talk to k8s-api directly? Or is this irrelevant?

I don't understand why is the information duplicated in the magnum db and
k8s data source in first place? From what I understand magnum has its own
database which is with k8s-api responses?
