I mentioned continuous queries and listener filters because you probably have some logic around keys that could be handled by these means. As an option, you could utilize Ignite messaging. Of course, you could have a separate cache containing only keys that you would update.
Could you describe what kind of logic you are trying to implement? What do you do once you have detected a key update? Kind regards, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
