            <title>[SERVER-71536] Investigate if non-replicated collections can skip RSTL lock</title>
                <link>https://jira.mongodb.org/browse/SERVER-71536</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As part of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-59673&quot; title=&quot;Investigate better solutions for fixing the deadlock issue in profiling&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-59673&quot;&gt;&lt;del&gt;SERVER-59673&lt;/del&gt;&lt;/a&gt; we&apos;ve introduced a function that provided a collection name tells whether it is safe to not take the RSTL lock for it in &lt;a href=&quot;https://github.com/mongodb/mongo/blob/0ec8f95180ad4b587e278501abd8841f0d475b79/src/mongo/db/repl/collection_utils.h#L44&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;collection_utils.h&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Initially this function will only contain the &lt;tt&gt;system.profile&lt;/tt&gt; collection, but ideally it should have others inside. For example non-replicated collections could go there as long as they aren&apos;t used by the replication system.&lt;/p&gt;

&lt;p&gt;We can&apos;t exclude all unreplicated collections from taking the RSTL lock because things like &lt;tt&gt;local.replset.election&lt;/tt&gt; and &lt;tt&gt;local.replset.minvalid&lt;/tt&gt; might not be safe for that. This ticket is to investigate further skipping RSTL acquisition for non-replicated collections when possible.&lt;/p&gt;</description>
