The memcached server doesn't do anything, it's the job of the client to distribute keys across the servers in a cluster. Having that distribution deterministic, i.e. that any client can figure out on which server a certain key is without communicating with the other clients is a good thing. If you were to alter the distribution runtime based on whatever keys happen to be stored right now, then all clients would have to communicate this somehow, and then you can forget about scaling linearly, and then why are you using memcached in the first place?
If your data distributes badly across your cluster, change your keys or your hashing algorithm until you're satisfied. /Henrik On Fri, Mar 4, 2011 at 12:55, Priya <priya.seh...@gmail.com> wrote: > Does memcached load balance, i.e., what if most of the keys hash to a > particular server, does memcached take some actions to load balance > it? >
