            <title>[SERVER-42574] Explain Plan: show regex performance (nr of steps)</title>
                <link>https://jira.mongodb.org/browse/SERVER-42574</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The Explain Plan is quite interesting. Maybe use a regex debugging library to compute the number of steps a regex takes to complete. For example: &lt;a href=&quot;https://metacpan.org/pod/Regexp::Debugger&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://metacpan.org/pod/Regexp::Debugger&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;The idea is to give the users the awareness of performance penalties for regular expression queries, especially complex ones that backtrack a lot.&lt;/p&gt;</description>
