<div>Hi</div>
<div>If we deploy Keystone using memcached as token backend we see that bringing down 1 of 3 memcache servers results in some tokens getting invalidated. Does memcached not support replication of tokens</div>
<div>So if we wanted HA w.r.t keystone tokens should we use SQL backend for tokens?</div>
