            <title>[SERVER-67845] Acquire critical section in rename &quot;check preconditions&quot; phase only if target not sharded</title>
                <link>https://jira.mongodb.org/browse/SERVER-67845</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The distributed lock is preventing overlaps between the critical section acquired by migrations and rename coordinators. As there is a plan to get rid of the distributed lock, purpose of this ticket is to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8b5272909338b6f5f68087f26b397e745440fde8/src/mongo/db/s/rename_collection_coordinator.cpp#L181-L190&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;acquire the critical section for the target collection&lt;/a&gt; only in case it is not sharded.&lt;/p&gt;

&lt;p&gt;This is fine because &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-67325&quot; title=&quot;Collection creation must be disallowed for collections undergoing a rename&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-67325&quot;&gt;&lt;del&gt;SERVER-67325&lt;/del&gt;&lt;/a&gt; introduced the acquisition of the critical section to avoid concurrent collections creation, but if a collection is already sharded that cannot happen.&lt;/p&gt;</description>
