            <title>[SERVER-79088] Improve SBE multi-planner performance for query which returns zero results</title>
                <link>https://jira.mongodb.org/browse/SERVER-79088</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;A $in query with multiple index choice and empty result is much slower after 6.3 upgrade, from the explain output we can tell that the problem is from SBE multi-planner. One of the predicate is an empty $in predicate &lt;tt&gt;descriptionRef:{ $in: []}{&lt;/tt&gt;}, we should think about whether there&apos;s anything we can do to improve the performance of the multi-planner in this scenario.&lt;/p&gt;</description>
