Yes. I do. Oh..ok. You are saying to do it the other way around, instead of passing a key and checking which server it belongs to, query every server in the list for a given key? I could that..not very optimal..but a workaround. Why I needed a way to get a server list where a particular key belongs to, it will be easy to check the state as well during run time. So whenever, some value fetch would give me an error, I could quickly use the key to get the servers its stored on and go on from there.
