            <title>[SERVER-78783] Reduce contention by including thread name in query stats store key</title>
                <link>https://jira.mongodb.org/browse/SERVER-78783</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This idea was floated by &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=schwerin%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;schwerin@mongodb.com&quot;&gt;schwerin@mongodb.com&lt;/a&gt; during the design review. I&apos;ve attached a prototype patch that didn&apos;t seem to show meaningful improvement. However, this might prove helpful or necessary depending on the outcome of ongoing investigations&lt;/p&gt;</description>

                            <comment id="5712916" author="JIRAUSER1274148" created="Mon, 18 Sep 2023 20:16:13 +0000"  >&lt;p&gt;As discussed, there is a potential read consistency issue if we introduce thread description as a part of the partition key. See &lt;a href=&quot;https://github.com/10gen/mongo/pull/15484&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/pull/15484&lt;/a&gt; for code that implements partitioning by thread description, based on Charlie&apos;s patch. By introducing thread description into the partition key, we now have to choose between holding partition locks for much longer (impractical) or accepting inconsistent reads (incorrect).&lt;/p&gt;</comment>
