            <title>[SERVER-42949] Move values inside InMemIterator::next()</title>
                <link>https://jira.mongodb.org/browse/SERVER-42949</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There is a simple optimization opportunity to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/05a99879a6369d6220356d099ac5625d359ffd4d/src/mongo/db/sorter/sorter.cpp#L145&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;move, rather than copy, elements when popping them from the deque&lt;/a&gt; in the InMemIterator. The value returned from &quot;_data.front()&quot; is copied, and then the original is immediately destructed with a call to &quot;pop_front()&quot;, which &lt;a href=&quot;https://en.cppreference.com/w/cpp/container/deque/pop_front&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;does not return the element&lt;/a&gt;.&lt;/p&gt;</description>
