<p>尽最大努力在集群范围内对给定的任务进行删除。</p>
<p>在网络连接良好并且所有节点都在线时，
这个命令的效果和 <code class="docutils literal"><span class="pre">ACKJOB</span></code> 命令的效果一样，
但是因为这个命令引发的消息交换比 <code class="docutils literal"><span class="pre">ACKJOB</span></code> 要少，
所以它的速度比 <code class="docutils literal"><span class="pre">ACKJOB</span></code> 要快不少。</p>
<p>但是当集群中包含了失效节点的时候，
<code class="docutils literal"><span class="pre">FASTACK</span></code> 命令比 <code class="docutils literal"><span class="pre">ACKJOB</span></code> 命令更容易出现多次发送同一消息的情况。</p>
