            <title>[SERVER-45215] Reads from default RWC cache shouldn&apos;t reuse user&apos;s read concern</title>
                <link>https://jira.mongodb.org/browse/SERVER-45215</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-43720&quot; title=&quot;mongos and configsvr get/setDefaultRWConcern commands&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-43720&quot;&gt;&lt;del&gt;SERVER-43720&lt;/del&gt;&lt;/a&gt;, the ReadWriteConcernDefaults cache reuses a command&apos;s operation context &lt;a href=&quot;https://github.com/mongodb/mongo/blob/176cc95d069b1d8a48bebca7872f293d014936f5/src/mongo/db/read_write_concern_defaults_cache_lookup_mongod.cpp#L40-L42&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;to look up the latest defaults from &lt;tt&gt;config.settings&lt;/tt&gt;&lt;/a&gt;. This read currently does not modify the read concern or read source of the operation context, but should instead always read from the latest snapshot to see the most recent defaults. This can possibly be done by using a ReadSourceScope object (introduced by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-40053&quot; title=&quot;Add an RAII type to change and restore the timestamp read source&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-40053&quot;&gt;&lt;del&gt;SERVER-40053&lt;/del&gt;&lt;/a&gt; and used when fetching a transaction&apos;s history) or an AlternativeClientRegion.&lt;/p&gt;</description>
