            <title>[SERVER-79357] CheckMetadataConsistency is not reading chunks with snapshot read concern</title>
                <link>https://jira.mongodb.org/browse/SERVER-79357</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;CheckMetadataConsistency command is &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b8e050ad94a6a584a15df5744c6ae59d216b42ac/src/mongo/db/s/config/configsvr_check_metadata_consistency_command.cpp#L210&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;correctly setting snapshot read concern&lt;/a&gt; when reading chunks from &lt;tt&gt;config.chunks&lt;/tt&gt; but since we are using the localCatalogClient (DBDirect client) the read concern provided &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b8e050ad94a6a584a15df5744c6ae59d216b42ac/src/mongo/db/service_entry_point_common.cpp#L1747-L1753&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;in the command gets ignored&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Possible solution are:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;use the normal CatalogClient, this will use remote command execution path that will honor the provided read concern&lt;/li&gt;
	&lt;li&gt;Set the read concern on the operation context before to invoking the DBDirectClient and reset once we reutrn from the call&lt;/li&gt;
	&lt;li&gt;We could also use an alternative client reagion so that we won&apos;t need to patch up the original operation context.&lt;/li&gt;
&lt;/ul&gt;
