KeyValue watch with callback

[dee909]

Hello,

Is there a way to watch a KeyValue with a callback instead of constantly wait for updates with a timeout ?
What I was expecting to find is something similar to a stream subscription with a callback argument.
(maybe I'm doing it completely wrong, the documentation couldn't help me on this)

Thanks for any insight !

I expected the same. It doesn't take a lot of code to implement what you want at least. Also see #580.
