database events or polling in nodejs (membase)
In my application I have a global state, which I distribute to different nodes on different servers through membase.

The nodes themselves have clients who need to be informed when the global state has been changed, but the only way I see is to poll the state from membase and send it to the client when changed. 
So I only have traffic between client and server when a change has happend, but I would have a constant traffic between the server and membase, which is not in the sens of the non-blocking IO of node.

Is there a better way?
