            <title>[SERVER-61560] simplify cursor initialization for unique key validation</title>
                <link>https://jira.mongodb.org/browse/SERVER-61560</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The validation code for verifying that a unique index contains no duplicates &lt;a href=&quot;https://github.com/mongodb/mongo/blob/339353e2af373accb2a866309e796124f91ba91c/src/mongo/db/catalog/validate_adaptor.cpp#L318&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;builds a KeyString&lt;/a&gt; to position the cursor at the beginning of the index. It would be nice to simplify this initial step of the index scan process.&lt;/p&gt;</description>

I think the ticket is not very relevant now.&lt;/p&gt;</comment>
                            <comment id="5233602" author="benety.goh" created="Mon, 27 Feb 2023 17:32:12 +0000"  >&lt;p&gt;The enhancement proposed in this ticket refers to code that has since been refactored in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-71061&quot; title=&quot;Ensure column index validation works&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-71061&quot;&gt;&lt;del&gt;SERVER-71061&lt;/del&gt;&lt;/a&gt; to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/72a56c27b43595e898ccdec5d859fe72b0d17135/src/mongo/db/catalog/validate_adaptor.cpp#L805&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;delegate the index traversal&lt;/a&gt; to the respective keystring/columnar index store consistency checkers.&lt;/p&gt;

&lt;p&gt;So it should be ok to close this ticket as Won&apos;t Do.&lt;/p&gt;</comment>
