Based on the keyname, a key/value pair gets hashed out to a particular
box. Consequently, any operations (add, set, get, delete, etc) for that
keyname are pinned to the same box.
If a server goes down, and you are pinned to it, then what depends on
the value of no_rehash. If no_rehash is true, then you're dead, as no
rehashing will take place. If no_rehash is false, then memcache will
rehash based on which servers it thinks are up. You can set no_rehash
using the set_norehash method.
You can find out about the above and other niceties by running the
command
perldoc Cache::Memcached
Good luck
