I am using ignite to manage my cluster.when node join I save an item in my NodeCache, when node left I delete an item in my NodeCache with ignite event listener. Use custom NodeCache but not ignite cluster topology,The reason is I want to keep node status persistence when node left for some restart operations. I have some problems 1. How to guarantee client node with same consistent(or other properties) do not join the cluster twice like server node works. 2. My nodes topology will have server 100+ client 2000+. how to make the cluster keep high stability.
