<dt class="optional">delay <span class="property-type">數值</span></dt>
|

<dd>設置要應用于消息的延遲（以毫秒爲單位）。僅當節點配置爲允許消息去覆蓋配置的默認延遲間隔時，此選項才適用。</dd>

<dt class="optional">reset</dt>
|
||
<dd>如果接收到的消息將此屬性設置爲任何值，則將清空該節點保留的所有的未發送消息。</dd>

<dt class="optional">flush</dt>

||
<dd>如果接收到的消息的此屬性設置爲任何值，則將立即發送該節點保留的所有未發送消息。</dd>

<h3>詳細</h3>
|
||
<p>當配置爲延遲發送消息時，延遲間隔可以是一個固定值，一個範圍內的隨機值或爲每個消息動態設置。</p>
|
||
<p>當配置爲對消息進行限制時，它們的傳遞將分散在配置的時間段內。狀態顯示隊列中當前的消息數。可以選擇在中間消息到達時丟棄它們。</p>
|
||
<p>速率限制可以應用于所有消息，也可以根據<code>msg.topic</code>的值來進行分組。分組時，中間消息將會被自動刪除。在每個時間間隔，節點可以釋放所有主題的最新消息，或釋放下一個主題的最新消息。</p>
