<p>Algorithm for distributing keys among two or more redis servers.</p>
<p>At the moment Rediska supports following modes:</p>
<ul>
<li><span class="pre">crc32</span> - simple and fast algorythm <span class="pre">crc32($keyName) % serversCount</span>.</li>
<li><span class="pre">consistentHashing</span> - <a href="http://weblogs.java.net/blog/tomwhite/archive/2007/11/consistent_hash.html">advanced algorithm</a> of distributing keys by servers.</li>
</ul>
<code>
require_once 'Rediska.php';
$options = array(
'keyDistributor' => 'crc32',
);
$rediska = new Rediska($options);
</code>
<p>By default Rediska uses <span class="pre">consistentHashing</span>.</p>
<h3>Custom algorithm</h3>
<p>You can use your own key distribution algorithm - just create a class implementing <span class="pre">Rediska_KeyDistributor_Interface</span> interface.</p>
<code>
require_once 'Rediska.php';
$options = array(
'keyDistributor' => 'YouPersonalClass',
);
$rediska = new Rediska($options);
</code>
