Your understanding is correct and you should get notifications. Do you get them with other cache modes, like REPL_SYNC?
Thanks for your reply, Manik! :)
I think my understanding may not be correct after all: at the time, I was trying to recieve a notification when a pair key-value was removed from inside a given node. And this is not possible, is it correct?
I now create a new node for each of my data and remove the node, which triggers the notifications correctly.
