            <title>[SERVER-53712] Implement mechanism to free documents in partition which are no longer needed</title>
                <link>https://jira.mongodb.org/browse/SERVER-53712</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This is a memory optimization to allow the PartitionIterator to detect when all consumers have accessed past a certain document, and thus the document can be released. &lt;/p&gt;

&lt;p&gt;Some options considered are:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;A registration mechanism for consumers, such that the iterator is aware of the greatest accessed index&lt;/li&gt;
	&lt;li&gt;Add an expire(int index) method such that the individual WindowManagers can signal when they&apos;re done with a document&lt;/li&gt;
&lt;/ul&gt;
