<p><strong>SINTERSTORE destination key [key ...]</strong></p>
<p>这个命令类似于 <a class="reference internal" href="sinter.html#sinter"><span>SINTER</span></a> 命令，但它将结果保存到 <code class="docutils literal"><span class="pre">destination</span></code> 集合，而不是简单地返回结果集。</p>
<p>如果 <code class="docutils literal"><span class="pre">destination</span></code> 集合已经存在，则将其覆盖。</p>
<p><code class="docutils literal"><span class="pre">destination</span></code> 可以是 <code class="docutils literal"><span class="pre">key</span></code> 本身。</p>
