            <title>[SERVER-69567] Investigate possibility of using WT_MODIFY for Oplog replication</title>
                <link>https://jira.mongodb.org/browse/SERVER-69567</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-69396&quot; title=&quot;Modify time-series inserts to use damages instead of full-document updates&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-69396&quot;&gt;SERVER-69396&lt;/a&gt; we will explore replacing the full-document updates of time-series insertions with WT_MODIFY application as it reduces the I/O used significantly.&lt;/p&gt;

&lt;p&gt;As normal Oplog updates already &lt;a href=&quot;https://github.com/mongodb/mongo/blob/25cc0c7a1b9078115a3b1785af4d6f7698e8f9af/src/mongo/db/ops/write_ops.cpp#L240&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;contain a Diff object&lt;/a&gt; sometimes, we could directly apply the computed damages instead of materializing the full document update.&lt;/p&gt;

&lt;p&gt;Note that this directly depends on &lt;a href=&quot;https://jira.mongodb.org/browse/WT-9668&quot; title=&quot;Improve overlap detection in WT_MODIFY paths&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-9668&quot;&gt;WT-9668&lt;/a&gt; and should only be started after the ticket gets resolved.&lt;/p&gt;</description>
