Hi everyone,

I have thought a bit on how to make sure that a particular key is distributed to ALL memcached servers in a pool.

My current, untested solution is to make another instance of memcached, something like this:

$cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50);

foreach ($this->cluster() as $cluster) {
    @$this->tempMemcache = new Memcache;
    @$this->tempMemcache->connect($cluster['host'], $cluster['port']);
    @$this->tempMemcache->set($key, $value, $this->compress, $expireTime);
    @$this->tempMemcache->close();
}

What is common sense to do in this case, when certain keys need to be stored on ALL servers for reliability?
