            <title>[SERVER-65015] Granular locks for synchronizing orphans tracking</title>

                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-64163&quot; title=&quot;Synchronize orphans tracking upon upgrade/downgrade with ongoing migrations&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-64163&quot;&gt;&lt;del&gt;SERVER-64163&lt;/del&gt;&lt;/a&gt; introduced a &lt;a href=&quot;https://github.com/mongodb/mongo/blob/3b106406facd601fff4f4607db74af626adab4ad/src/mongo/db/s/range_deletion_util.cpp#L698-L700&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;generic lock on the range-deleter collection&lt;/a&gt; for synchronizing orphans update and range deletions. Purpose of this ticket is to implement a more granular locking mechanism in order to parallelize concurrent orphans updates and range deletions. The granularity could be at range level (very granular, lock by migrationId) or at least at collection level (less granular, lock by collection UUID).&lt;/p&gt;</description>
