            <title>[SERVER-46205] Remove the direct dependency of CollectionShardingState on CatalogCache/ChunkManager</title>
                <link>https://jira.mongodb.org/browse/SERVER-46205</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The work for &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-32198&quot; title=&quot;Missing collection metadata on the shard implies both UNSHARDED and &amp;quot;metadata not loaded yet&amp;quot;&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-32198&quot;&gt;&lt;del&gt;SERVER-32198&lt;/del&gt;&lt;/a&gt; will decouple the direct dependency of non-sharding code on &lt;a href=&quot;https://github.com/mongodb/mongo/blob/95c8fc6a4a98f70b07f32565e3ef3e48172efa1e/src/mongo/db/s/collection_metadata.h#L49&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;CollectionMetadata&lt;/tt&gt;&lt;/a&gt; and all the interactions of non-sharding consumers with sharding will be going only through &lt;a href=&quot;https://github.com/mongodb/mongo/blob/95c8fc6a4a98f70b07f32565e3ef3e48172efa1e/src/mongo/db/s/collection_sharding_state.h#L61&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;CollectionShardingState&lt;/tt&gt;&lt;/a&gt; and specifically through the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/95c8fc6a4a98f70b07f32565e3ef3e48172efa1e/src/mongo/db/s/scoped_collection_metadata.h#L83&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;getOwnershipFilter&lt;/tt&gt;&lt;/a&gt; and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/95c8fc6a4a98f70b07f32565e3ef3e48172efa1e/src/mongo/db/s/scoped_collection_metadata.h#L41&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;getCollectionDescription&lt;/tt&gt;&lt;/a&gt;&#160;interfaces.&lt;/p&gt;

&lt;p&gt;This work in this ticket is one level below the &lt;tt&gt;CollectionShardingState&lt;/tt&gt; implementation on shards and is to remove all dependencies from &lt;tt&gt;CollectionShardingState&lt;/tt&gt; on &lt;tt&gt;CollectionMetadata&lt;/tt&gt; and push that interaction to be done through calls to the &lt;b&gt;FilteringMetadataService&lt;/b&gt;.&lt;/p&gt;

&lt;p&gt;After this ticket is done, there should be no more &lt;tt&gt;CollectionMetadata&lt;/tt&gt; calls and the &lt;tt&gt;MetadataManager&lt;/tt&gt; can be thrown out.&lt;/p&gt;</description>
