The reason I am trying to do this is for better debugging. In case something goes wrong in the system and I am unable to get the value stored for a particular key, I can go ahead and use this functionality to understand on which server that particular key is stored. Also, the second question about why the printing doesn't work. Is there any other way to check on which server a key is stored. Additionally, when you say brute force, how would I be able to do it on memcached server as I will not know on which server instance the key is stored. Could you please elaborate on this?
