            <title>[SERVER-47982] Change the shard version update procedure of the migration source manager</title>
                <link>https://jira.mongodb.org/browse/SERVER-47982</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As part of&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-47987&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;SERVER-47987&lt;/a&gt; the way the cache is refreshed will be changed on a more &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-47975&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;optimized&lt;/a&gt; and safe way using a new &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-47974&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;scoped object&lt;/a&gt;. All this work will end on the removal of &lt;a href=&quot;https://github.com/mongodb/mongo/blob/736bf1bca376a50dbd038098baf0a2f6ace29db7/src/mongo/db/s/shard_filtering_metadata_refresh.h#L96&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;forceShardFilteringMetadataRefresh&lt;/a&gt;, which will make the local cache of a shard consistent with the config server. As part of this process the migration source manager needs to set the filtering metadata within the critical section, and should ensure:&lt;/p&gt;

&lt;p&gt; 1. If the operation fails, it must set the collection metadata to unknown, so the real shard version can be recovered lazily when needed.&lt;br/&gt;
 2. There must not be any unnecessary refresh of the metadata after committing the new shard version, it should simply set the new shard version.&lt;br/&gt;
 3. There must not be any recovery. &lt;/p&gt;</description>
