            <title>[DOCS-15553] Investigate changes in SERVER-62760: Add information to query log line indicating when the new optimizer is used</title>
                <link>https://jira.mongodb.org/browse/DOCS-15553</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;1. Rename the `queryExecutionEngine` field to `queryFramework` in the $serverStatus output, the slow query log, and the system.profile entries.&lt;/p&gt;

&lt;p&gt;2. Add an additional possible value (&quot;cqf&quot;) for the `queryFramework` field.&lt;/p&gt;

&lt;p&gt;This change will be backported to 6.0.&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;

&lt;p&gt;null&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;FROMDOCS15061&quot;&gt;&lt;/a&gt;&lt;b&gt;FROM &lt;a href=&quot;https://jira.mongodb.org/browse/DOCS-15061&quot; title=&quot;Investigate changes in SERVER-60848: Log which engine was used for processing a query&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DOCS-15061&quot;&gt;&lt;del&gt;DOCS-15061&lt;/del&gt;&lt;/a&gt;&lt;/b&gt;&lt;/h2&gt;

&lt;p&gt;NOTE: &lt;a href=&quot;https://jira.mongodb.org/browse/DOCS-15061&quot; title=&quot;Investigate changes in SERVER-60848: Log which engine was used for processing a query&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DOCS-15061&quot;&gt;&lt;del&gt;DOCS-15061&lt;/del&gt;&lt;/a&gt; has been closed and instead combined with &lt;a href=&quot;https://jira.mongodb.org/browse/DOCS-15553&quot; title=&quot;Investigate changes in SERVER-62760: Add information to query log line indicating when the new optimizer is used&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DOCS-15553&quot;&gt;&lt;del&gt;DOCS-15553&lt;/del&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Related to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-60848&quot; title=&quot;Log which engine was used for processing a query&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-60848&quot;&gt;&lt;del&gt;SERVER-60848&lt;/del&gt;&lt;/a&gt;&lt;/p&gt;
&lt;div class=&quot;panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;&quot;&gt;&lt;b&gt;Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot;&gt;
&lt;p&gt;This patch makes changes to the slow query log line as well as the serverStatus counters. It also changes the system.profile collection, which will have identical fields to the new slow query log line. This change will also be backported to 5.2.&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;

&lt;p&gt;Add a field that indicates whether we used classic or SBE for a query. We should backport it to 5.1. At the least we want to see how many queries are exposed to SBE.&lt;/p&gt;

&lt;p&gt;Worth considering:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;just logging a field if the less common case happens (e.g. &quot;sbe&quot;)&lt;/li&gt;
	&lt;li&gt;should we use the same field in the future for the optimizer (e.g. &quot;sbe&quot; (executed with sbe) / &quot;cqf&quot; (optimized and executed with cqf)&lt;/li&gt;
&lt;/ul&gt;
