            <title>[SERVER-82283] Consider removing optimize call from $expr rewriter</title>
                <link>https://jira.mongodb.org/browse/SERVER-82283</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;tt&gt;ExprMatchExpression&lt;/tt&gt;&apos;s optimizer in &lt;tt&gt;ExprMatchExpression::getOptimizer()&lt;/tt&gt; function first &lt;a href=&quot;https://github.com/10gen/mongo/blob/7ee58e38418ae603cfdaa2bd224ca50118985443/src/mongo/db/matcher/rewrite_expr.cpp#L65&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;calls $expr rewriter&lt;/a&gt; to rewrite its child expression and then &lt;a href=&quot;https://github.com/10gen/mongo/blob/7ee58e38418ae603cfdaa2bd224ca50118985443/src/mongo/db/matcher/expression_expr.cpp#L223&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;calls optimize()&lt;/a&gt; on a new expression which includes the rewritten expression.&lt;/p&gt;

&lt;p&gt;The $expr rewriter &lt;a href=&quot;https://github.com/10gen/mongo/blob/7ee58e38418ae603cfdaa2bd224ca50118985443/src/mongo/db/matcher/rewrite_expr.cpp#L71&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;calls optimize()&lt;/a&gt; on the rewritten expression as well.&lt;/p&gt;

&lt;p&gt;One of the two calls seems to be redundant, please consider if one the calls can be safely removed.&lt;/p&gt;</description>
