            <title>[SERVER-64038] Allow MODE_IX multi-collection locking in the AutoGet* helpers because multi-document transaction reads use MODE_IX</title>
                <link>https://jira.mongodb.org/browse/SERVER-64038</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://github.com/10gen/mongo/pull/3461#&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;SERVER-62798&lt;/a&gt;&#160;currently must exclude multi-doc transactions because of &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8696ce442652f7a69232b35901b73684bbcf7a88/src/mongo/db/catalog_raii.cpp#L163-L174&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this invariant&lt;/a&gt;&#160;that multi-collection locking is MODE_IS only.&lt;/p&gt;

&lt;p&gt;Remove the multi-doc trans exclusion in run_aggregate.cpp necessitated by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-62798&quot; title=&quot;Use AutoGetCollectionMulti in MultiCollection helper&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-62798&quot;&gt;&lt;del&gt;SERVER-62798&lt;/del&gt;&lt;/a&gt; along with this work.&lt;/p&gt;</description>
