            <title>[SERVER-63691] Optimize lookup of array elements in local when lowering $lookup into NLJ in SBE</title>
                <link>https://jira.mongodb.org/browse/SERVER-63691</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;A na&#239;ve implementation would traverse the array for each record in the foreign table. This might or might not be a problem. Should measure and, if necessary, optimize it by repacking the array or keys into a set.&lt;/p&gt;</description>
