title: Can magento use multiple MySQL slaves?
body: <p>The following is part of my config for using a single slave. </p>
  
  <pre><code>&lt;default_read&gt;                 
      &lt;connection&gt;               
          &lt;use/&gt;                 
          &lt;host&gt;&lt;![CDATA[slavedb1.amazonaws.com]]&gt;&lt;/host&gt;
          &lt;username&gt;&lt;![CDATA[username]]&gt;&lt;/username&gt;
          &lt;password&gt;&lt;![CDATA[Password]]&gt;&lt;/password&gt;
          &lt;dbname&gt;&lt;![CDATA[shop]]&gt;&lt;/dbname&gt;
          &lt;initStatements&gt;&lt;![CDATA[SET NAMES utf8]]&gt;&lt;/initStatements&gt;
          &lt;model&gt;&lt;![CDATA[mysql4]]&gt;&lt;/model&gt;
          &lt;type&gt;&lt;![CDATA[pdo_mysql]]&gt;&lt;/type&gt;
          &lt;pdoType&gt;&lt;![CDATA[]]&gt;&lt;/pdoType&gt;
          &lt;active&gt;1&lt;/active&gt;  
      &lt;/connection&gt;
  &lt;/default_read&gt;
  </code></pre>
  
  <p>However, I want to use <strong>multiple slaves</strong>. Is this possible with Magento?</p>
  
  <p>To clarify, I have already got a single master/slave setup working with Magento already. I want to add another slave so that I have two slaves. I am wondering how the config will change to make use of this second slave.</p>
