                <link>https://jira.mongodb.org/browse/SERVER-53509</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As part of writing noop oplog entries on the recipient,&#160;use TransactionParticipant (and config.transactions) itself to cache the OpTime of the last noop oplog entry for each session to create an oplog chain for retryable writes and update config.transactions.&lt;/p&gt;

&lt;p&gt;The noop oplog entry should contain &quot;fromMigrate: true&quot; and contain the original oplog entry in the &quot;o2&quot; field so that the SessionUpdateTracker on secondaries &lt;a href=&quot;https://github.com/mongodb/mongo/blob/9e91eac734db8840a9190f4d5bf9a5c320b3ab28/src/mongo/db/repl/session_update_tracker.cpp#L171-L177&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;recognizes&lt;/a&gt; the noop oplog entry as a retryable write oplog entry and updates its config.transactions.&lt;/p&gt;</description>

&lt;p&gt;Edit: nope, it&apos;s intentional.  Oplog entry will contain both.&lt;/p&gt;</comment>
