            <title>[SERVER-57496] Proactively evict cached entries after drop database/collection</title>
                <link>https://jira.mongodb.org/browse/SERVER-57496</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Both drop database and drop collection on sharded cluster currently only invalidate the information on the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/1c2b0f685aa3c035f43f4ecc924a42a50534f620/src/mongo/db/s/shardsvr_drop_database_participant_command.cpp#L88-L94&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;DatabaseShardingState&lt;/a&gt; and the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/1c2b0f685aa3c035f43f4ecc924a42a50534f620/src/mongo/db/s/sharding_ddl_util.cpp#L361-L368&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;CollectionShardingRuntime&lt;/a&gt; after the database/collection have been dropped. The rename collection operation also &lt;a href=&quot;https://github.com/mongodb/mongo/blob/1c2b0f685aa3c035f43f4ecc924a42a50534f620/src/mongo/db/s/rename_collection_participant_service.cpp#L97-L104&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;cleans up the CollectionShardingRuntime&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;This is enough to ensure that subsequent requests will be causal consistent with the DDL operation.&lt;/p&gt;

&lt;p&gt;In order to free-up some memory, we should also proactively evict the cached entries for the dropped db/coll or renamed coll in the catalog cache.&lt;/p&gt;</description>
