            <title>[SERVER-57307] Improve deletion of config.chunks entries with hint and retries</title>
                <link>https://jira.mongodb.org/browse/SERVER-57307</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-57221&quot; title=&quot;Inconsistent delete performance on collections with multiple secondary indexes on same key&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-57221&quot;&gt;&lt;del&gt;SERVER-57221&lt;/del&gt;&lt;/a&gt; highlighted performance problems on deletes for collections with more than one secondary index, showing that using an index hint can lead to better performance.&lt;/p&gt;

&lt;p&gt;As collections may have a lot of chunks:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Extend the catalog client in order to optionally accept an optional hint as argument for &lt;a href=&quot;https://github.com/mongodb/mongo/blob/be505f3601c0fe8c7c29411f09927b0d153a22db/src/mongo/s/catalog/sharding_catalog_client.h#L339&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;removing config documents&lt;/a&gt;.&lt;/li&gt;
	&lt;li&gt;Update the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/be505f3601c0fe8c7c29411f09927b0d153a22db/src/mongo/db/s/sharding_ddl_util.cpp#L103-L104&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;delete chunks call&lt;/a&gt; to pass a proper hint.&lt;/li&gt;
	&lt;li&gt;As &lt;tt&gt;NetworkInterfaceExceededTimeLimit&lt;/tt&gt; can be hit in case of slow deletes, implement a retry logic for this specific case (just needed for legacy path, since &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-57311&quot; title=&quot;Make ShardingDDLCoordiantor retry on ExceededTimeLimit errors&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-57311&quot;&gt;&lt;del&gt;SERVER-57311&lt;/del&gt;&lt;/a&gt; is addressing the problem for DDL coordinators).&lt;/li&gt;
&lt;/ul&gt;
