            <title>[SERVER-77842] Cache IndexCatalogEntry during the collection scan phase of an index build</title>
                <link>https://jira.mongodb.org/browse/SERVER-77842</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77062&quot; title=&quot;Perform copy-on-write of index catalog entries when cloning a collection&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77062&quot;&gt;&lt;del&gt;SERVER-77062&lt;/del&gt;&lt;/a&gt; introduced copy-on-write semantics for IndexCatalogEntry and removed cached pointers. This has introduced noticeable performance regressions during the collection scan phase of an index build. We can safely cache the IndexCatalogEntry here to get this performance back.&lt;/p&gt;</description>
