            <title>[DOCS-16497] Investigate changes in SERVER-79848: Difference in behavior of $_resumeAfter between classic and SBE engines</title>
                <link>https://jira.mongodb.org/browse/DOCS-16497</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;    This patch makes it so that both the classic engine and SBE obey the following semantics for the $_requestResumeToken and $_resumeAfter  query options:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;For $_requestResumeToken,  &apos;null&apos; is returned as the resumeToken after scanning the last document in a collection (prior to this patch, SBE would return the record id of the last document).&lt;/li&gt;
	&lt;li&gt;When a null RecordId is specified to $_resumeAfter, we raise a KeyNotFound error (prior to this patch, the classic engine would restart the scan from the beginning).
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    When resuming from the last record in a collection, the classic engine returns resume token {&quot;$recordId&quot; : null} and SBE returns the last record.&lt;br/&gt;
Resuming from {&quot;$recordId&quot; : null} in the classic record cycles back to the start of the collection and raises &quot;KeyNotFound&quot; error in SBE.&lt;/p&gt;&lt;/li&gt;
&lt;/ul&gt;
