            <title>[SERVER-58362] Refactor SSCCL&apos;s functions purging cached collection metadata</title>
                <link>https://jira.mongodb.org/browse/SERVER-58362</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In order to rationalize the code that access the persistent cache managed by SSCCL, the &lt;tt&gt;dropChunksIfEpochChanged&lt;/tt&gt; function can be removed and instead take advantage of the &lt;tt&gt;dropChunksAndDeleteCollectionsEntry&lt;/tt&gt; function. The latter deletes both the collection entity and the chunks collection from the persistent cache, which will be then appropriately recreated later.&lt;/p&gt;

&lt;p&gt;This comes from&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-34632&quot; title=&quot;config.chunks change to config.cache.chunks creates a collection long name after upgrade&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-34632&quot;&gt;SERVER-34632&lt;/a&gt;&apos;s &lt;a href=&quot;https://mongodbcr.appspot.com/798010001/diff/775620001/src/mongo/db/s/shard_metadata_util.cpp#newcode458&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;code review&lt;/a&gt;.&lt;/p&gt;</description>
