            <title>[SERVER-81294] Switch AutoGetCollectionForReadMaybeLockFree for acquireCollectionsMaybeLockFree in DocumentSourceCursor</title>
                <link>https://jira.mongodb.org/browse/SERVER-81294</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The current multi-collection acquire path offered by &lt;tt&gt;AutoGetCollectionForReadLockFree&lt;/tt&gt; violates a fundamental sharding requirement that all referenced namespaces pre-declare a placement concern (db or shard version). Because of this, they are not safe to use with a concurrent shardCollection or movePrimary.&lt;/p&gt;

&lt;p&gt;This ticket is to switch the two usages in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b056792924792503fa3cee9855284cc2a9dea018/src/mongo/db/pipeline/document_source_cursor.cpp#L175&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;DocumentSourceCursor&lt;/a&gt; to the new acquisitions API.&lt;/p&gt;</description>
