                    <description>&lt;p&gt;Based on discussion &lt;a href=&quot;https://groups.google.com/forum/#!topic/mongodb-dev/Y4N7Pe76BKs&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://groups.google.com/forum/#!topic/mongodb-dev/Y4N7Pe76BKs&lt;/a&gt; , a cursor doesn&apos;t need to be positioned to anywhere when created.&lt;/p&gt;

&lt;p&gt;Remove unnecessary seek after creating RocksCursor can significantly improve performance in some cases.&lt;/p&gt;</description>
