Hi Alexey, I think the best way is to keep this meta-data in node attributes [1]. You can acquire the attribute value for any node at any moment via ClusterNode.attribute(..) method. In case you want to do some checks on startup, you can utilize lifecycle beans [2]. Let me know if it works for you.
