            <title>[DOCS-15704] Investigate changes in SERVER-67024: Re-enable NLJ for $lookup pushed down into SBE</title>
                <link>https://jira.mongodb.org/browse/DOCS-15704</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;    This ticket will expand the cases in which $lookup can be pushed down and executed in SBE.&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    Once &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-65960&quot; title=&quot; Fall back to classic engine when NLJ is chosen&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-65960&quot;&gt;&lt;del&gt;SERVER-65960&lt;/del&gt;&lt;/a&gt; is merged, the use of NLJ will be hidden behind &apos;featureFlagSbeFull&apos; ($lookups eligible for NLJ will fall back to the classic engine instead). This ticket tracks the work to re-enable NLJ once the performance improves.&lt;/p&gt;

&lt;p&gt;Closing this ticket as a result, but feel free to ping if this should/needs to be re-opened.&lt;/p&gt;</comment>
