            <title>[SERVER-49496] Refactor CatalogCache::_scheduleCollectionRefresh function</title>
                <link>https://jira.mongodb.org/browse/SERVER-49496</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The &lt;a href=&quot;https://github.com/mongodb/mongo/blob/51604da9f47a7d58a72cf58cbfb28c4a2340642e/src/mongo/s/catalog_cache.cpp#L676-L824&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;CatalogCache::_scheduleCollectionRefresh&lt;/a&gt; logic is implemented using a mix of callbacks and recursion. This makes particularly difficult to follow the execution flow.&lt;br/&gt;
Moreover this code is even more difficult to follow because the result forwarded to the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/910176bb6f0283504a56bf50a869866359704c3a/src/mongo/s/catalog_cache.cpp#L764&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;callback &lt;/a&gt;is handled by an &lt;a href=&quot;https://github.com/mongodb/mongo/blob/910176bb6f0283504a56bf50a869866359704c3a/src/mongo/s/catalog_cache.cpp#L770-L771&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;internal function&lt;/a&gt; and not from the main callback logic.&lt;/p&gt;

&lt;p&gt;Once&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-49292&quot; title=&quot;Futurify CatalogCacheLoader API&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-49292&quot;&gt;&lt;del&gt;SERVER-49292&lt;/del&gt;&lt;/a&gt; is committed this function should be refactored in order to address the outlined issues.&lt;/p&gt;
