Why kvm can store oauth token?
because kvm should store value that don’t expire. but oauth token can expire.
The KVM is a store for anything.
I suppose you could store a token there. You’d be responsible for removing it though.
Probably not a good idea to store a token in the KVM. Apigee manages the tokens;; there’s no need for you to design your proxy to explicitly store them.
I see you’re asking about “why” it’s possible to store a thing in the KVM. That’s sort of a philosophical question; it’s not very concrete.
If you have a specific thing you want to accomplish, maybe you could ask about THAT THING and we’ll try to help you
