Hello, OK. How do you use these registries after that?
I don't think that there is a need to keep version in the key. Ignite guarantees that a cache contains the latest version at each moment. Probably the only things you need to keep in the key object are id and type. Even if you need to handle version explicitly it should be placed inside the value object. Since you need some kind of registry of (probably) not very big volume, a replicated cache could come in handy. You then could populate it on remote nodes if you *definitely* need to propagate the keys. Kind regards, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
