            <title>[SERVER-25536] Investigate performance impact of parsing pipeline within the collection lock</title>
                <link>https://jira.mongodb.org/browse/SERVER-25536</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We moved the parsing of the aggregation pipeline to within the collection lock as part of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-25038&quot; title=&quot;Comparisons made by $bucket at parse time must respect the collation&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-25038&quot;&gt;&lt;del&gt;SERVER-25038&lt;/del&gt;&lt;/a&gt;. On storage engines that support document-level locking, this isn&apos;t likely to be a problem, since the lock will only be an intent lock. On storage engines like MMAPv1, there may be some noticeable overhead, which we should investigate and maybe attempt to mitigate.&lt;/p&gt;</description>
