            <title>[SERVER-78359] [CQF] Mark full index scans as low priority</title>
                <link>https://jira.mongodb.org/browse/SERVER-78359</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;After &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-72440&quot; title=&quot;Deprioritize collection scans under load&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-72440&quot;&gt;&lt;del&gt;SERVER-72440&lt;/del&gt;&lt;/a&gt;, full collscans and index scans are marked as low priority in classic (and in SBE via the stage builders). &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77792&quot; title=&quot;[CQF] Mark full collscans as low priority&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77792&quot;&gt;&lt;del&gt;SERVER-77792&lt;/del&gt;&lt;/a&gt; made sure CQF did the same for full collscans. This ticket is to handle full index scans in CQF. &lt;a href=&quot;https://github.com/10gen/mongo/blob/1e54a90b429056573199b995a2cc2386aabdc56f/src/mongo/db/exec/sbe/abt/abt_lower.cpp#L1251-L1263&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;This code&lt;/a&gt; should be changed to set low priority when the interval is fully open.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://github.com/10gen/mongo/blob/1e54a90b429056573199b995a2cc2386aabdc56f/jstests/noPassthrough/index_scan_low_priority.js#L1&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;This&lt;/a&gt; is the jstest that covers this behavior.&lt;/p&gt;</description>
