            <title>[DRIVERS-642] Mongos drain mode</title>
                <link>https://jira.mongodb.org/browse/DRIVERS-642</link>
                <project id="10980" key="DRIVERS">Drivers</project>
                    <description>&lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-color: #ccc;border-style: dashed;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;border-bottom-style: dashed;border-bottom-color: #ccc;background-color: #239eb0;&quot;&gt;&lt;b&gt;Epic Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;

&lt;p&gt;Offer a drain mode for mongos which allows existing queries to continue and prevent new work from starting.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;Motivation&lt;/h4&gt;

&lt;p&gt;In service of offering no impact for planned maintenance, we need a method to remove a mongos from a rotation without adversely affecting user operations&lt;/p&gt;
