            <title>[SERVER-75490] Use kSnapshotReadConcern when getting chunks from config server at checkMetadataConsistency</title>
                <link>https://jira.mongodb.org/browse/SERVER-75490</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The goal of this ticket is to investigate and try to use &lt;tt&gt;kSnapshotReadConcern&lt;/tt&gt; instead of &lt;tt&gt;kMajorityReadConcern&lt;/tt&gt; in &lt;a href=&quot;https://github.com/10gen/mongo/blob/acf902a082d40b0ee6caa350ab1e6023703f4a3b/src/mongo/db/s/config/configsvr_check_metadata_consistency_command.cpp#L125-L138&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;_getCollectionChunks&lt;/tt&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;For the moment, ShardingCatalogClient::getChunks is using &lt;a href=&quot;https://github.com/10gen/mongo/blob/d0a76b2b3ea3f5800cb9023fbb83830288569f8f/src/mongo/db/rs_local_client.cpp#L93&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;queryOnce&lt;/a&gt; to get the chunks. &lt;a href=&quot;https://github.com/10gen/mongo/blob/d0a76b2b3ea3f5800cb9023fbb83830288569f8f/src/mongo/db/rs_local_client.cpp#L144&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Here&lt;/a&gt;, there is an invariant invalidating the usage of &lt;tt&gt;kSnapshotReadConcern&lt;/tt&gt;. &lt;/p&gt;</description>
