            <title>[SERVER-71689] Refresh the CatalogCache before dropping the local collection</title>
                <link>https://jira.mongodb.org/browse/SERVER-71689</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The goal of this task is to change how &lt;a href=&quot;https://github.com/mongodb/mongo/blob/afdbfe0fffbacc2559cc94af5e1bde3e57cb34e2/src/mongo/db/s/drop_collection_coordinator.cpp#L51-L126&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;sharded local collections are dropped&lt;/a&gt;. We can see this function as a sequence of three operations:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/afdbfe0fffbacc2559cc94af5e1bde3e57cb34e2/src/mongo/db/s/drop_collection_coordinator.cpp#L70-L73&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Clear the in-memory filtering metadata&lt;/a&gt;.&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/afdbfe0fffbacc2559cc94af5e1bde3e57cb34e2/src/mongo/db/s/drop_collection_coordinator.cpp#L107-L115&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Dropping the local Collection&lt;/a&gt;.&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/afdbfe0fffbacc2559cc94af5e1bde3e57cb34e2/src/mongo/db/s/drop_collection_coordinator.cpp#L119-L121&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Clearing the routing information (in-memory and persisted (i.e. &lt;tt&gt;config.cache.*&lt;/tt&gt;))&lt;/a&gt;.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;The idea is to swap 2 and 3, so we clear the routing information first and then we drop the local collection, so if the collection to be dropped doesn&apos;t exist on that shard (i.e. &lt;a href=&quot;https://github.com/mongodb/mongo/blob/afdbfe0fffbacc2559cc94af5e1bde3e57cb34e2/src/mongo/db/s/drop_collection_coordinator.cpp#L111-L116&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;in this&lt;/a&gt; path we throw an exception &lt;a href=&quot;https://github.com/mongodb/mongo/blob/afdbfe0fffbacc2559cc94af5e1bde3e57cb34e2/src/mongo/db/s/shardsvr_drop_collection_participant_command.cpp#L94-L99&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;that is captured in an upper level&lt;/a&gt;) we don&apos;t forget to clear the routing information (i.e. we don&apos;t leave garbage behind).&lt;/p&gt;

&lt;p&gt;Affected versions: all versions since 5.0&lt;b&gt;.&lt;/b&gt;&lt;/p&gt;</description>
