            <title>[SERVER-38695] Make QuerySolutionNode subclasses for projection fast-paths</title>
                <link>https://jira.mongodb.org/browse/SERVER-38695</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-37831&quot; title=&quot;Optionally decouple WorkingSetMember from projection evaluation&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-37831&quot;&gt;&lt;del&gt;SERVER-37831&lt;/del&gt;&lt;/a&gt; find projection execution has been separated into three classes: one with the full implementation and two with different fast paths. We should create corresponding QuerySolutionNode subclasses because we want a one-to-one correspondence between PlanStages subclesses and these. Intuitively we want the planner to have direct knowledge of which implementation it is choosing.&lt;/p&gt;</description>
