            <title>[COMPASS-7462] Investigate changes in SERVER-82274: singleBatch find on a timeseries collection does not close cursor if batchSize is set</title>
                <link>https://jira.mongodb.org/browse/COMPASS-7462</link>
                <project id="13182" key="COMPASS">Compass </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;    In the very specific case you run a command over a view with the configuration &quot;db.runCommand({find: &apos;myview&apos;, filter: {}, singleBatch: true, batchSize: 1, limit: 1})&quot; (with those flags and values specifically), in versions 7.2 and earlier the server will return a cursor. If you ran any getMores with that cursor it would return no results and the cursor would be closed. With this change, in v7.3 and beyond, the server will not return a cursor on that initial command.&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;    When using a TimeSeries collection if a find command has &lt;tt&gt;batchSize:1&lt;/tt&gt; and &lt;tt&gt;singleBatch:true&lt;/tt&gt; the cursor returned is not closed, it reports a non-zero id. If the batchSize is omitted then the cursor will be closed. The same behavior is not observed for a typical collection, the id returned is always zero when &lt;tt&gt;singleBatch&lt;/tt&gt; is set.&lt;/p&gt;
