            <title>[DOCS-11131] Recommend setting maxTimeMS and document timeout behavior for mongos</title>
                <link>https://jira.mongodb.org/browse/DOCS-11131</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;We had a lengthy discussion with engineering about the behavior of &lt;em&gt;mongos&lt;/em&gt; on timeout. It appears that the &lt;em&gt;mongos&lt;/em&gt; and drivers rely heavily on the &lt;tt&gt;maxTimeMS&lt;/tt&gt; cursor and connection level setting. Drivers do not monitor this and rely on the server/&lt;em&gt;mongos&lt;/em&gt; to terminate connections on erratic server behavior.&lt;/p&gt;

&lt;p&gt;This should be documented because developers should care (or at least think) about timeout failure situations. Additionally, we should recommend setting the &lt;tt&gt;maxTimeMS&lt;/tt&gt; setting at the driver level when using sharded clusters.&lt;/p&gt;

&lt;p&gt;Details here:&lt;br/&gt;
