            <title>[SERVER-45109] Modify AsyncDBClient to allow exhaust requests</title>
                <link>https://jira.mongodb.org/browse/SERVER-45109</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Many functions on AsyncDBClient chain via &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/client/async_client.cpp#L196-L227&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;_call()&lt;/a&gt;. To allow AsyncDBClient to serve exhaust responses, we need to separate out the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/client/async_client.cpp#L215-L226&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&quot;source&quot; part&lt;/a&gt; of its pattern as &lt;tt&gt;_waitForResponse()&lt;/tt&gt;. We can then write &lt;tt&gt;runExhaustCommand()&lt;/tt&gt;/&lt;tt&gt;runExhaustCommandRequest()&lt;/tt&gt; commands that call the &quot;source&quot; part as long as &lt;tt&gt;OpMsg::kMoreToCome&lt;/tt&gt; is set. To test this, we&apos;ll want a trivial command that we can treat as exhaust with little other logic: &lt;tt&gt;sleep&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt; In summary, there are three parts:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Make &lt;tt&gt;sleep&lt;/tt&gt; an exhaust command&lt;/li&gt;
	&lt;li&gt;Write and integrate &lt;tt&gt;AsyncDBClient::_waitForResponse()&lt;/tt&gt; to allow tailing.&lt;/li&gt;
	&lt;li&gt;Test &lt;tt&gt;AsyncDBClient::runExhaustCommand()&lt;/tt&gt; with &lt;tt&gt;sleep&lt;/tt&gt; in integration test.&lt;/li&gt;
&lt;/ul&gt;
