            <title>[SERVER-63020] Investigate relevance of SERVER-31978 to per shard cursors</title>
                <link>https://jira.mongodb.org/browse/SERVER-63020</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;I stumbled across &lt;a href=&quot;https://github.com/10gen/mongo/blob/0c14c06ba8916b0c7c7b137771cbfca8f95beff2/src/mongo/db/pipeline/document_source_change_stream_transform.cpp#L159&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this&lt;/a&gt; comment which mentioned the linked ticket and seems to imply there may be issues with arm not being prepared for a cursor to close prematurely. Per shard change stream cursors don&apos;t need to coordinate across shards so some of these warnings may be irrelevant.&lt;/p&gt;</description>

                            <comment id="4359625" author="JIRAUSER1258420" created="Wed, 16 Feb 2022 19:04:21 +0000"  >&lt;p&gt;After discussion with Charlie and Bernard, it seems that this invariant is no longer relevant, since &lt;tt&gt;DocumentSourceCloseCursor&lt;/tt&gt; has been removed. The invariant and the comment are probably safe to delete, and the Per Shard Cursors project doesn&apos;t need to worry about it. I&apos;ve filed &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-63745&quot; title=&quot;Delete outdated invariant in DocumentSourceChangeStreamTransform::applyTransformation&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-63745&quot;&gt;&lt;del&gt;SERVER-63745&lt;/del&gt;&lt;/a&gt; to delete the invariant and comment.&lt;/p&gt;</comment>
