            <title>[SERVER-85088] POC: Explore ways we can shrink the generated oplog entries from pipeline-style updates</title>
                <link>https://jira.mongodb.org/browse/SERVER-85088</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The existing update system has a fairly sophisticated way of tracking damages performed by an update to generate a minimal oplog entry. We have a fairly sophisticated system within aggregation to detect which fields are modified by which stages - we may be able to re-use it to inform oplog entry generation.&lt;/p&gt;</description>

We have a rough POC &lt;a href=&quot;https://mongodbcr.appspot.com/544180001&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;&#160;which doesn&apos;t handle $unsets which could be interesting and different, but we don&apos;t think there&apos;s remaining value in this ticket, so we&apos;ll call it complete.&lt;/p&gt;</comment>
