            <title>[SERVER-82817] Implement corresponding Stage Builder changes for Window Function to optimize projections</title>
                <link>https://jira.mongodb.org/browse/SERVER-82817</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-81466&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;SERVER-81466&lt;/a&gt;improves how projections are generated by Stage Builder. It was merged Nov 4th. Stage Builder for window function can use this change to optimize the partition expressions for $linearFill to avoid redundant $project/addFields.&lt;/p&gt;

&lt;p&gt;The limitation placed in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-83490&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-83490&lt;/a&gt; should be removed as part of this work.&lt;/p&gt;</description>
