            <title>[SERVER-41942] Clear partialTxnList when committing a prepared transaction.</title>
                <link>https://jira.mongodb.org/browse/SERVER-41942</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When applying oplog entries that were a part of a large transaction, we first add them to partialTxnList and then apply them during the commit. We then clear partialTxnList for the next large transaction.&lt;/p&gt;

&lt;p&gt;Currently, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6cb22a4feef4e5eb03412e392d2274707965f9b9/src/mongo/db/repl/sync_tail.cpp#L1254&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;we do not&lt;/a&gt; clear partialTxnList when committing a prepared transaction. This means that for large prepared transactions, partialTxnList will have entries that were not part of the same transaction.&lt;/p&gt;

&lt;p&gt;As a part of this ticket, we should also make sure to test the bug in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-41163&quot; title=&quot;During initial sync, failing to apply an update thats in a prepared txn hits an invariant&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-41163&quot;&gt;&lt;del&gt;SERVER-41163&lt;/del&gt;&lt;/a&gt; with large transactions. We can use initial_sync_update_missing_doc.js for this.&lt;/p&gt;</description>
