            <title>[SERVER-11997] User cache is invalidated too often and too crudely</title>
                <link>https://jira.mongodb.org/browse/SERVER-11997</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;On mongod the entire internal user cache is invalidated every time a user or role is updated. &lt;/p&gt;

&lt;p&gt;On mongos the internal user cache is invalidated every ten minutes whether it&apos;s necessary or not.&lt;/p&gt;

&lt;p&gt;In an ideal world:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;The cache should only be updated when an actual relevant change is made.&lt;/li&gt;
	&lt;li&gt;Only the portion of the cache that was changed should be updated.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;This one deals with performance, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-11980&quot; title=&quot;Improve user cache invalidation enforcement on mongos&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-11980&quot;&gt;&lt;del&gt;SERVER-11980&lt;/del&gt;&lt;/a&gt; with security.&lt;/p&gt;</comment>
